PROBLEM TO BE SOLVED: To provide a method that can reduce the degree of the gap between the optical axes of two optical members due to temperature change more than when the optical members are fixed to a fixing member of a material different from that of the optical members with the fixing member in between.SOLUTION: The method for manufacturing an optical component 40 includes the steps of: forming a lens 54 and an optical member 50 by injecting resin from one side of a longer direction, the lens 54 being long-sized and having a plurality of convex parts LS protruding into an optical axis direction and arranged along the longer direction, and the optical member 50 having a pair of side plates protruding from both sides of the lens 54 in a shorter direction to both sides of the optical axis direction; and positioning the ends of two optical members 50 at the same side, bringing the side plates in contact with each other and fixing the side plates so that the optical axes of the center parts of the convex parts LS overlap with one another.SELECTED DRAWING: Figure 3 |
