Zusammenfassung: | An biological body information acquisition apparatus includes an imager including light emitting devices that are arranged in a plane and emit light toward a human body and light receiving devices that are arranged in a plane and receive light from the human body and a light guide plate that is layered on the imager on the side thereof facing the human body and has light transmissivity in the direction of a normal to the light receiving devices and the light emitting devices. The light guide has a first portion (holes) and a second portion (substrate) that are arranged in a plane and have refractive indices different from each other. The first portion (holes) is so disposed as to coincide with the light receiving devices in a plan view, and the second portion (substrate) is so disposed as to coincide with the light emitting devices in the plan view. |
