Abstract

The present invention provides a vehicle lamp comprising a lens molded article () and a housing molded article () laser-welded to each other, the lens molded article () comprising a methacrylic resin composition which comprises 70 to 99.9% by mass of a methacrylic acid ester monomer unit and 0.1 to 30% by mass of a unit of an additional vinyl monomer copolymerizable with the methacrylic acid ester monomer and satisfies conditions (a) to (c), and the housing molded article () comprising a resin which satisfies a condition (d): (a) MW is 90000 to 250000; (b) a mass (MFR-1) of the methacrylic resin composition emitted according to ISO1133 standard at 230° C. and 3.8 kg for 10 minutes is 0.2 to 12 g/10 min; (c) when a mass of the methacrylic resin composition emitted according to the ISO1133 standard at 230° C. and 10 kg for 10 minutes is defined as MFR-2, MFR ratio=(MFR-2)/(MFR-1) is 4.5 or more; and (d) a mass (MFR-3) of the resin emitted according to the ISO1133 standard at 220° C. and 10 kg for 10 minutes is 2 to 45 g/10 min or smaller.
