An imaging device capable of picking up a wide range from a plurality of imaging units, providing a good image quality, and being downsized. The imaging device (20) comprises a plurality of imaging units (1) each provided with an imaging element (3) and a lens front cell (2), wherein adjacent imaging units (1) are so disposed as to allow their imaging areas to be overlapped, and, when a section passing through a view point center, an imaging element (3), and a lens front cell (2) in this overlapping direction is assumed, a conditional expression, AL < fD (1), is satisfied and the view point center of each imaging unit (1) is disposed within a 20-mm sphere; where the section length of the imaging element (3) is A, the section length of the lens front cell (2) D, the distance from the lens front cell (2) to the imaging element (3) L, a focal distance obtained by combining the entire lens in the imaging unit (1) including the lens front cell (2) f. |
