Abstract: An optical path-changing member comprises a member main body which is made of a transparent material and in which a reflection section optically connecting the optical fiber to the light input and output end is formed, wherein the reflection section is a first lens having a concave shape when viewed from an incident direction and making light incident on the inside of the member main body from one of the optical fiber and the light input and output end be internally reflected in the member main body and directed to the other of the optical fiber and the light input and output end, a second lens having a convex shape toward the optical component is formed in a light incidence and emission surface of the member main body, that faces the optical component.
