In the camera 10 having an ultraviolet light generating portion 16, the influence of the ultraviolet light upon an image to be taken is suppressed. A camera 10 for taking an image possesses an image-pickup portion 24 which takes an image of a subject; a hydrophilic filter 14 formed so that a hydrophilic surface is exposed on an outer surface of the camera, and transmitting a light entering from the subject to said image-pickup portion; and an ultraviolet light generating portion 16, which irradiates an ultraviolet light with the surface of the external surface of said camera on said hydrophilic filter from the edge portion of said hydrophilic filter. The hydrophilic filter 14 comprises a photocatalytic substance which decomposes organic substances adhered thereon depending on the ultraviolet light.
