Abstract
A light source device includes a light-condensing device that condenses an illumination light that is emitted from a light source lamp. The light-condensing device includes at least one lens, a lens holder in which a lens is fixedly provided, and a lens holding member. The lens holding member is a member for fixing a lens to the lens holder. The lens holding member causes at least one circumferential portion of the lens to protrude to the lens holder side, and causes the optical axis of the lens to match the optical axis of the illumination light.
