A transformer includes a multilayer board including insulation layers stacked in a thickness direction, a primary coil provided on at least one of the insulation layers, and a secondary coil provided on at least one of the insulation layers. The primary coil includes first sub coils electrically connected in series to each other, and second sub coils electrically connected in series to each other. Surfaces of the plurality of insulation layers constitute layer planes of the multilayer board. At least two of the first sub coils are provided on layer planes out of the layer plane different from each other. At least two of the second sub coils are provided on layer planes out of the layer planes different from each other. An average of positions of the first sub coils in the thickness direction is aligned with an average of positions of the second sub coils in the thickness direction.

An infrared sensor includes an infrared detecting device, a lens, a member, a gap and a spacer. The lens is disposed above the infrared detecting device. The member forms an external surface and includes a first opening having a maximum internal diameter. The gap is disposed between the member and the lens. The spacer is disposed between the member and the lens so as to form the gap, and that is directly contact with lens. The spacer has a circular inner periphery, in planar view, which has a larger internal diameter than the maximum internal diameter of the first opening of the member.

Infrared sensor

An infrared sensor includes: an infrared detecting device; a lens disposed above the infrared detecting device; an member that is disposed at a side of an upper surface of the lens and includes an opening; and a gap that intervenes between the member and the lens and has a wider range than the opening.

A portable terminal includes a case, a display unit having a display screen exposed from a front surface of the case, and a skin-condition measurement sensor accommodated in the case. The skin-condition measurement sensor includes a measurement unit provided on the front surface of the case. The portable terminal can be carried and operate easily.
