An RFID tag board includes an insulating substrate provided with a first surface conductor, a second surface conductor, a short-circuit part through conductor, a capacitance conductor, a capacitance part through conductor, a first electrode and a second electrode. The short-circuit part through conductor electrically connects the first surface conductor and the second surface conductor. The capacitance conductor faces at least part of one of the first and second surface conductors to form a capacitance element. The capacitance part through conductor electrically connects the capacitance conductor and the other one of the first and second surface conductors. First and second conductors of the capacitance element are electrically connected to the first and second electrodes, respectively, not via the short-circuit part through conductor. A distance from the first electrode to the short-circuit part through conductor is shorter than a distance from the second electrode to the short-circuit part through conductor.

A measurement sensor package and a measurement sensor reduce susceptibility to noise and enable highly accurate measurement. A measurement sensor package includes a substrate. The substrate includes a first recess including a first bottom surface on which a light emitter is mountable, and a first step surface having a first connection pad thereon, a second recess including a second bottom surface on which a light receiver is mountable, and a second step surface having a second connection pad thereon. In a direction connecting a center of the first bottom surface and a center of the second bottom surface in a plan view, the first step surface is located outward from the first bottom surface and the second step surface is located outward from the second bottom surface.

Measurement sensor package and measurement sensor

A measurement sensor package and a measurement sensor reduce susceptibility to noise and enable highly accurate measurement. A measurement sensor package () includes a substrate (), a lid (), and a ground conductor layer (). The substrate () contains a light emitter and a light receiver, and includes a substrate body (), a plurality of ground via conductors (), an frame-shaped ground conductor layer (), signal wiring conductors (), and an external connection terminal (). The ground via conductors () are connectable to a ground potential, and are located outward from a first recess () and a second recess () included in the substrate body () in a plan view.

A measurement sensor package and a measurement sensor improve reliability in strength and other aspects. A measurement sensor package includes a substrate, a lid, a ground conductor layer, a metallic thin layer, and a bond. The ground conductor layer and the metallic thin layer are arranged inside the bond that extends continuously as viewed through from above. The bond directly bonds a first main surface of a substrate body and a facing surface of the lid together along the entire periphery. This improves the reliability in strength.

An electronic device, a display method in an electronic device, and a non-transitory computer readable recording medium are disclosed. A charging coil generates induced electromotive force by interlinkage of a magnetic field from an external charger coil with the charging coil. A battery is to be charged with the induced electromotive force. A display includes a display region, a position that coincides with the center of the charging coil being located inside an outline of the display region in plan view. At least one processor displays, in the display region, a charging screen including information that indicates the center of the charging coil in the position when an operation is performed on the operation unit while the battery is charged with the induced electromotive force.

A charging coil generates induced electromotive force by interlinkage of a magnetic field from an external charger coil with the charging coil. A battery is to be charged with the induced electromotive force. A display includes a display region. A position that coincides with the center of the charging coil is located inside an outline of the display region in plan view. When the battery is charged with the induced electromotive force in a first mode that shuts off a supply of direct-current voltage from the battery to the display, at least one processor supplies the direct-current voltage to the display, and displays, in the display region, a first charging screen including first information that indicates the center of the charging coil in the position. The at least one processor ends the display of the first charging screen after a lapse of a predetermined period of time.
