An upper flexible board mounts a circuit. A lower flexible board is in a plate shape larger than a circuit mounting unit, is connected to the upper flexible board by a connecting part, is bent so that the connecting part faces a face opposite to a mounting face of the circuit of the upper flexible board, and includes an area from a bend that is generated by bending an area that does not overlap with the upper flexible board including a second end different from the connecting part to the second end. An iris illuminating LED is disposed on the same side as the upper flexible board in the area. An iris photographing camera is disposed at a position separated from the iris illuminating LED by a certain distance or more and acquires an image of an iris that has received light emission from the iris illuminating LED.

A light guide mechanism for an illuminance sensor includes: a lighting window configured to pass through an external light; the illuminance sensor configured to detect an illuminance of the light passed through the lighting window; and a light-blocking part provided between the lighting window and the illuminance sensor and configured to block a light other than the light passed through the lighting window. The light-blocking part has an inner surface inclined with respect to a line perpendicular to a light-receiving surface of the illuminance sensor. A direction of inclination of the inner surface is such that the inner surface faces the light-receiving surface of the illuminance sensor.
