PROBLEM TO BE SOLVED: To provide an angle adjustment mechanism of an optical component in which both of an angle adjustment function and a heat radiation function are achieved with a simple constitution even when the optical component is accompanied by heat generation.SOLUTION: An angle adjustment mechanism 1 includes: a spherical body 5 that has a shape such that a part of a sphere is cut and holds an optical component 2 on a planer side; a heat radiation member 6 that is installed on a spherical surface side of the spherical body 5; and a base 7 for attaching the spherical body 5. In the base 7, a cylindrical penetrating base hole 8 is included that is in contact with a spherical surface portion of the spherical body 5. By making the spherical body 5 in contact with the base hole 8 and rotating the spherical body 5, an inclination angle of the optical component 2 is adjusted. In addition, heat generated in the optical component 2 is passed from the heat radiation member 6 through the base hole 8 to be released from a rear surface side of the base 7. |
