Abstract
A sterilization apparatus is provided at a discharge port for supplying a liquid. The sterilization apparatus includes: an annular light guide that has a connection end that is connected to the discharge port and an open end that is on the opposite side of the connection end, and that forms a flow passage communicating with the discharge port; and a light source that allows ultraviolet light to enter the light guide such that the ultraviolet light is transmitted through the light guide while being reflected between an inner circumferential surface and an outer circumferential surface of the light guide. The sterilization apparatus irradiates a liquid that is in contact with the inner circumferential surface of the light guide with the ultraviolet light for sterilization.
