PROBLEM TO BE SOLVED: To provide an imaging module for endoscopes capable imaging under optimal observation conditions according to an observation purpose (an observation site), suppressing the number of components as much as possible, dispensing with a focus adjustment time of lens, reducing the manufacturing cost as much as possible and improving the manufacturing efficiency. SOLUTION: This imaging module for endoscopes is provided with a basic module 10 consisting of a convex lens 11 and an image pickup device 12 whose mutual positions are fixed, and a plurality of optical modules 20 (21 and 22) selectively attached to the basic module 10; and changes over the observation conditions according to the selectively attached optical module. The respective modules 21 and 22 are so constituted that, when being attached to the basic module 10, an image position of the light of the observation image to the image pickup device 12 and an oblique incidence angle are almost same.
