Abstract
The invention aims to provide small-sized and highly-reliable light converter and light source unit, as well as a projector each of which makes it possible to cool down heat generated in a fluorescent body in a motorless manner. A light converter of the disclosure includes a fluorescent body that is excited by excitation light; a first light-collecting lens that has a lens surface to which the fluorescent body is bonded, and causes the excitation light to enter the fluorescent body; and a heat-dissipating member to which the lens surface is adhered at least around a region to which the fluorescent body is bonded.
