PROBLEM TO BE SOLVED: To provide an imaging device which comprises an optical system suitable for thinning and in which moire stripes are hardly formed. SOLUTION: An imaging device of the present invention comprises: at least three color filters, including first to third color filters 9R, 9G and 9B having respectively different filtering characteristics; at least three lens systems, including first to third lens systems 2R, 2G and 2B respectively associated with the first to third color filters, and a photodetection section including a first photodetector 4R for receiving light transmitted through the first color filter 9R and the first lens system 2R, a second photodetector 4G for receiving light transmitted through the second color filter 9G and the second lens system 2G, and a third photodetector 4B for receiving light transmitted through the third color filter 9B and the third lens system 2B. Each of the first to third photodetectors 4R, 4G and 4B has a two-dimensional array of photodetection cells such that centers of the photodetection cells are positioned at a piece of triangles sharing respective sides with one another, where none of three corner angles of each triangle is equal to 90°.
