PROBLEM TO BE SOLVED: To provide an imaging device that obtains proper optical performance without hindering reduction in size while easily securing sealing performance around an optical element without reducing a degree of freedom in design of a housing.SOLUTION: The imaging device 10 includes: a lens barrel 30; an imaging element 52; a mounting wall part 11 that forms an outer surface S surrounding one end (31) of the lens barrel 30 in a direction orthogonal to an imaging optical axis O; a connection member 54 for connecting the imaging element 52 to the lens barrel 30 by screwing to allow relative movement in the direction of the imaging optical axis O with respect to the lens barrel 30; a first fixing means (23, 31) to fix the mounting wall part 11 and the lens barrel 30 to each other by fixing operation from the radial direction while the one end of the lens barrel 30 is pressed against the mounting wall part 11 in the direction of the imaging optical axis O; and a second fixing means (24) to fix the connection member 54 to the lens barrel 30 by fixing operation from the radial direction while the imaging element 52 is connected to the other end (32) of the lens barrel 30 through the connection member 54. |
