Light-receiving module for encoder, and encoder

A light-receiving module for an encoder, the light-receiving module comprising:

• a support body having a bottom wall part and a side wall part disposed on a main surface of the bottom wall part on one side of the bottom wall part;
• a light-receiving element having a light-receiving surface, disposed on the main surface of the bottom wall part such that the light-receiving surface faces the one side, and surrounded by the side wall part when viewed from the one side;
• and
• a fiber optic plate having an input surface constituted by surfaces of one end of a plurality of optical fibers and an output surface constituted by surfaces of the other end of the plurality of optical fibers and disposed on the light-receiving element such that the output surface faces the light-receiving surface,
• wherein, when viewed from a direction along the main surface of the bottom wall part, an end surface of the side wall part on the one side is positioned more distant to the one side than the light-receiving surface with respect to the main surface of the bottom wall part, and the input surface is positioned more distant to the one side than the end surface with respect to the main surface of the bottom wall part.
