Claim:
1. A method of manufacturing a package for mounting a light emitting element, the package including a pair of lead electrodes made of metal plates and a resin molded body and having a recess portion in which a light emitting element is mounted, the recess portion being formed of the pair of lead electrodes and the resin molded body, and the pair of lead electrodes being exposed on a bottom surface of the recess portion and at least one of the pair of lead electrodes has a groove portion that is formed along a periphery of the metal plate exposed on the bottom surface of the recess portion, the method using a mold including an upper mold having a projection portion having a shape corresponding to the recess portion and a lower mold on which the pair of lead electrodes to be placed, wherein the projection portion having a protrusion portion that extends from a surface of the projection portion and protrude vertical to the surface of the projection portion and wherein the protrusion portion extending from the surface of the projection portion of the upper mold is located at at least a periphery of the surface of the projection portion, the method comprising: placing a pair of lead electrodes in a predetermined position on the lower mold, fitting the upper mold with the lower mold so that the pair of lead electrodes set between the upper mold and the lower mold and that the protrusion portion abuts on at least one of the pair of lead electrodes, pressing the upper mold against the pair of lead electrodes, injecting resin into the mold being in contact with the pair of lead electrodes; curing the injected resin to harden the resin molded body; and removing the upper mold from the lower mold, wherein, in the pressing of the pair of lead electrodes between the upper mold and the lower mold, the groove portions are formed at the pair of lead electrodes by the protrusion portion extending from the surface of the projection portion of the upper mold.
