PROBLEM TO BE SOLVED: To efficiently condense lights incident on an optical waveguide, irrespective of the position of pixels in a solid state imaging device. SOLUTION: The solid state imaging device (30) is composed of a plurality of pixels disposed on an expected image forming plane of a photographing lens. Each pixel has a microlens (31), a light receiver (33) for converting an incident light to an electric signal, and an optical waveguide (37) made of a transparent high-refractive index material disposed between the microlens and the receiver to guide the light from the microlens to the receiver. The optical waveguide has a different shape (37a-37d) suited to the position of each pixel in the imaging device, and the shape meets the condition that the incident light from the microlens makes the total reflection in the optical guide means.
