A process is for laser-welding resinous members, and includes the steps of overlapping a transparent resinous member on an absorptive resinous material, and irradiating the transparent resinous member with a laser beam, thereby welding an interface between the transparent resinous member and the absorptive resinous member as a strip shape, wherein the energy of the laser beam acting on a side of a major-curvature-radius curved part of the strip-shaped welded interface and the energy of the laser beam acting on a side of a minor-curvature-radius curved part thereof are averaged.
