To provide an endoscope cleaner capable of allowing droplets adher to a lid to flow into a cleaning tub.

The endoscope cleaner comprises the cleaning tub and the lid 4 for opening and closing the opening of the cleaning tub. The lid 4 is attached to the cleaner so as to be turned through a hinge and opened and closed, and a through-hole 40 is formed at the bottom of a groove part 51b formed of the top plate part 41, upper peripheral wall part 42a and lower peripheral wall part 42b of the lid 4 on the rear side 4Bof the lid 4 to which the hinge is attached. In the lid 4 in an opened state, the upper peripheral wall part 42a has such an inclination that both side parts 56 and 57 near the through-hole 40 get down toward the vicinity.
