Abstract

An optical-element angle adjustment device includes: a first protruding portion and a second protruding portion formed to protrude on the same axis from opposite positions across an optical mirror held by a mirror holding portion; a first adjustment member having an elongated hole formed along a direction corresponding to a first rotation direction representing a direction in which the axis is rotated, in which the second protruding portion is inserted; and a second adjustment member fitting with the second protruding portion protruding from the first adjustment member. A position of the second protruding portion in the elongated hole is adjusted using the first adjustment member. An angle of rotation of the second adjustment member in a second rotation direction with the axis as a rotation axis is adjusted. Thereafter positions of the first adjustment member and the second adjustment member are fixed.
