Abstract
A microwave-excited light source device according to the present application comprises: a center electrode that extends in an axial direction; an annular electrode that is disposed concentrically with respect to the center electrode; an arc tube that is disposed in an annular space formed between the center electrode and the annular electrode and extends along the axial direction in an elongated shape: a connection end plate to which the other pole of a microwave generation source is electrically connected; a connector that electrically connects the annular electrode and the connection end plate; and a buffer that is elastically deformed when the arc tube is subjected to an external force, thereby suppressing stress to be applied to a contact surface between the annular electrode and the connector.
