1. A light-source apparatus comprising: a light-source chip; a case in which the light-source chip is received; a first electrically-conductive part and a second electrically-conductive part each of which is apart of the case and located on opposite ends; a substrate to which the case is mounted; an electromagnetic shield plate covering at least part of the substrate, the first and second electrically-conductive parts and the case; an electrically-conductive layer formed on the substrate and electrically connected with both the second electrically-conductive part and the electromagnetic shield plate; and an electrically-conductive unit electrically connecting the first electrically-conductive part and the electromagnetic shield plate, wherein the case is interposed between the substrate and the electromagnetic shield plate; and the electrically-conductive unit is located outside an irradiation region within which light is irradiated by the light-source chip.
