RFID tag

An RFID tag includes a circuit board, an RFID IC, a functional module, a case and a lid. The circuit board has a main part and an extended part. The extended part extends along an edge of the main part and includes an antenna conductor. The RFID IC is mounted on the circuit board. The functional module is disposed so as to overlap the circuit board. The case accommodates the circuit board and the functional module. The lid closes an opening of the case. The main part of the circuit board is held at a position away from an inner bottom surface of the case with the functional module as an obstacle in a direction toward the lid.

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.

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.
