Abstract
A projector includes a first lens plate having a plurality of lenses, a second lens plate having a plurality of lenses, a light valve that modulates an output light beam from the second lens plate, and a light source apparatus. The light-source apparatus has a light-source lamp including an emission tube, a reflective mirror that reflects a divergent light beam from the light-source lamp to output a parallel light beam, the reflecting mirror having a reflective surface, a lamp housing that supports the reflective mirror, and an electrode lead. The electrode lead is led out of an end of the emission tube that is projected forward out of the reflective surface and is connected to an external connection terminal board which is positioned to a rear side of the reflective surface. The electrode lead is routed via the portion of the reflective mirror other than an effective area of the reflective mirror. A portion of the electrode lead positioned on the side of the reflective surface is arranged along a grove of a lens of the plurality of lenses of one of the first and second lens plate.
