Patent ID: 8777469

Claim:
A method of manufacturing a vehicular lamp comprising manufacturing a light source module by a method comprising: forming a recess portion on one face of a substrate such that a part of an end edge of the recess portion conforms to a part of a side edge of the substrate, and an unformed portion not having the recess portion therein is maintained on the one face of the substrate; disposing a light emitting diode on the recess portion of the substrate; disposing a pair of power supply members on the unformed portion of the substrate; forming a connecting portion on the substrate; connecting the light emitting diode and the pair of power supply members; and wherein the substrate is manufactured by: providing a base substrate having a plate form and an area at least twice as large as an area of the substrate; countersinking a base recess into the base substrate such that no part of an end edge of the base recess conforms to any part of a side edge of the base substrate; and cutting the base substrate through the base recess so as to form at least two light source modules.
