Abstract
Exemplary embodiments provide a light source unit capable of reducing emission of any unnecessary electromagnetic waves to a sufficient level, and a projector using such a light source unit. Exemplary embodiments include a chip that emits light responding to an incoming current, a base section structured by stacking the chip, electrode terminals to supply the current to the chip, and a cap section made from an optically transparent member to seal both the chip, and the electrode terminals, and a bonding wire. The base section and the cap section are both made from a conductive member, and the chip, the bonding wire, and the electrode terminals are electromagnetically enclosed through sealing by the base section and the cap section.
