PROBLEM TO BE SOLVED: To provide an imaging unit that can suppress deflection of an imaging element caused by a change in temperature without adding members.SOLUTION: An imaging unit 10 comprises a long imaging element 11 that extends along a surface parallel to an imaging surface 11a, a circuit board 12 that forms a circuit for driving the imaging element 11, and fixing members 14 that fix the imaging element 11 and circuit board 12. On the circuit board 12, in the same type of straight lines (r1, r2, and r3) extending in the longitudinal direction DI of the imaging element 11 on which the plurality of fixing members 14 are located, at least one through hole 15 orthogonal to the longitudinal direction DI and passing through the circuit board 12 is provided, and the through hole 15 is located between the two fixing members 14 on the straight line.SELECTED DRAWING: Figure 6 |
