A metal halide lamp emitting ultraviolet light having a wavelength of 350 to 380 nm, which comprises : an air-tight container (11) comprising an ultraviolet light-permeable quartz glass and being provided with an air-tight discharge space (10); a pair of discharge electrodes (121, 122) that are positioned in the air-tight container and face each other along the axial direction; and an enclosed material comprising a rare gas in an amount sufficient for maintaining the arc-discharged state in the discharge space, mercury and an appropriate amount of thallium and a halogen capable of providing ultraviolet light emission.  By irradiating an ultraviolet light-curable resin composition containing a photopolymerization initiator with the ultraviolet light emitted from the aforesaid metal halide lamp, the curing speed of the resin composition can be increased.
