Abstract

To take an image of a subject while suppressing glares or shadows, a light emitting section is provided with a plurality of light emitting elements. A light source section is arranged in a subject side of the light receiving section, and is provided with a light emitting section that illuminates the subject and a plurality of transmissive sections that transmits incident light to the light receiving section side. The light emitting section is provided with a first translucent layer, which includes a light emitting layer, and a reflection layer and a semi-transmissive reflection layer, which are opposed each other interposing the first translucent layer, so that a resonance structure that resonates irradiation light from the light emitting layer is formed. Each of the transmissive sections is provided with a second translucent layer, and a first semi-transmissive reflection layer and a second semi-transmissive reflection layer, which are opposed each other interposing the second translucent layer, so that a resonance structure that resonates incident light from the subject side is formed. A resonance length between the reflection layer and the semi-transmissive reflection layer in the light emitting section is more than a resonance length between the first semi-transmissive reflection layer and the second semi-transmissive reflection layer in the transmissive section.
