IMAGING DEVICE AND ILLUMINATION DEVICE

摘要

PROBLEM TO BE SOLVED: To increase the amount of light produced by a light-emitting unit.SOLUTION: An imaging device 100 comprises a light-receiving unit 10 in which a plurality of light-receiving elements 14 are arranged; and a light source unit 36 disposed between the light-receiving unit 10 and a subject 200. In the light source unit 36, light-emitting units 50 for irradiating the subject 200 with light, and transmission units 60 for transmitting light originating from the subject 200 to the light-receiving unit 10 side are arranged in a planar configuration. At least a part of the rim of the light-emitting unit 50 has a shape that conforms to the rim of the transmission unit 60 in plan view. Specifically, the rim of the transmission units 60 has a circular shape, and the rim of the light-emitting unit 50 has an arcuate shape concentric to the rim of the transmission unit 60.
