PROBLEM TO BE SOLVED: To provide a compact and slim skin observation device in which proximity illumination is enabled and the irradiation angle for every light emitting elements is facilitated.SOLUTION: The skin observation device includes LEDs 5 located at equal intervals in the peripheries of a base part 4 made of resin as a plurality of light emitting elements for emitting light to the center of the base part 4, a mirror 12 for reflecting light from LEDs 5 to a skin observation port 10c of housing 10, an imaging lens 7 incorporated in an opening 4a through which light reflected from the skin S passes at the center of base part 4, and an imaging element 8 fixed to the base part 4 on the optical axis L of the imaging lens 7. At the bottom face 4b of the base part 4, eight recessed parts 11 are formed extending in the radial direction around the opening 4a. Within each recessed part 11, the mirror 12 is placed, and LEDs 5 are placed in the outer end in the radial direction of each recessed part 11. The mirrors 12 located on an optical axis between the LEDs 5 and the polarizing filter 2 have a one-to-one relationship in the recessed parts 11.
