Abstract:
1. A discharge lamp comprising: a glass member that is formed to extend in a first direction and houses electrodes for electric discharge; a first base member that is coupled to one end portion of the glass member in the first direction; a cover member that is formed with an electrically conductive material, the cover member having a flat part which is placed on the first base member and a cylinder part which covers a side surface of the first base member; a flow path bending member that is formed with an electrically conductive material, the flow path bending member being mounted to the flat part and formed with a flow path extending in the first direction from a direction that intersects with the first direction; a connector that is electrically connected to the flow path bending member, the connector having a cylindrical electrically conductive material formed with a supply path for supplying a cooling medium to the flow path; and a second base member that is coupled to another end portion of the glass member in the first direction, wherein a flange part is provided at one end portion of the second base member; and a first shaft part is provided between the flange part and another end portion of the second base member, an outer shape of the first shaft part with respect to a direction orthogonal to the first direction being smaller than that of the flange part.
