Summary:A housing for an optical element has a first holding surface contact holding a first surface of an optical element and a second holding surface contact holding a ridge line separated from the first surface of the optical element. A first pressing member presses the optical element toward the first holding surface, and a second pressing member presses the optical element toward the second holding surface. An intersection angle obtained by extrapolating and extending the first and second holding surfaces is an acute angle, and a first pressing position at which the first pressing member presses on the optical element is closer to the second holding surface than to a center of the optical element. A second pressing position at which the second pressing member presses on the optical element is farther from the first holding surface than from the center of the optical element.
