PROBLEM TO BE SOLVED: To suppress the occurrence of a flare phenomenon though a front cover is made transparent. SOLUTION: The front cover 42 is molded from transparent resin. The front surface of a lens holder 25 holding a photographing lens 3 is covered with a lens presser 46 and the lens 3 is interposed between them. Then, an aperture 47 restricting light made incident on the lens 3 is formed at the front surface part of the presser 46. Besides, a light shielding wall 48 engaged in a lens aperture 28 formed at the cover 42 so as to cover the inside circumferential wall surface 28a of the aperture 28 extending over the whole surface is projectingly formed at the circumferential edge part of the aperture 47. Thus, even when the wall surface part 28a of the aperture 28 shines because the transparent cover 42 is exposed to external light, light radiated therefrom is prevented from being made incident on the lens 3 because the optical path thereof is shielded by the wall 48.
