Abstract

A light-source unit includes: a discharge lamp (3) that has a discharge space (13) containing mercury as a filling; and a housing (5), where the discharge lamp (3) is provided inside the housing (5). The housing (5) includes a reflecting member (7) and a lens member (9). The housing (5) includes a cutting (7e) and a through hole (43a) which enable the inside and outside of the housing (5) to communicate with each other. A cutting absorber (45a) is attached to the cutting (7e), and a through hole absorber (45b) is attached to the through hole (43a). The cutting absorber (45a) and the through hole absorber (45b) contain activated charcoal that absorbs mercury.
