Abstract

A mercury-free vehicle discharge bulb (10) is provided. The discharge bulb includes an arc tube (12) a glass shroud (14) extending in a front-rear direction to cylindrically surround the arc tube, a metal band (16) surrounding and holding a rear end portion of the glass shroud, and an insulating plug (18) supporting the glass shroud in a fixed manner via the metal band. A ratio S1/S2 of a first area S1 to a second area S2 is 1 to 3. The first area S1 is a surface area of an outer surface of the glass shroud in a region from a circumference of the glass shroud at a position of a center of the discharge space (24) to a front end edge (16c) of the metal band, and the second area S2 is a surface area of a surface of the metal band that touches the glass shroud.
