Abstract
A method of manufacturing a vehicle lamp includes providing a housing having a front opening and a transparent cover having a curved front face and a rear face having a welding face portion. The welding face portion of the transparent cover is placed in a closely contacting state with respect to the housing and the transparent cover is joined with the housing so as to close the front opening of the housing by irradiating a welding light ray toward the welding face portion through the transparent cover. The placing includes applying a pressing force against the housing to the transparent cover in a predetermined direction such that an angle of the welding face portion of the transparent cover with respect to the predetermined direction is closer to a right angle than an angle of the front face of the transparent cover corresponding to the welding surface with respect to the predetermined direction.
