Abstract:
1. A light-emitting device production method comprising: a mounting step of mounting, by wire bonding, at least one light-emitting element on a substrate; a positioning step of positioning a sealing member so that the sealing member faces an upper surface of the at least one light-emitting element mounted in the mounting step, the sealing member being solid, maintaining a predetermined shape, and at least containing a silicone resin semi-cured by primary cross-linking and a fluorescent material; a melting step of melting, by heating at a temperature lower than a secondary cross-linking temperature at which the silicone resin subjected to primary cross-linking is totally cured by secondary cross-linking, the sealing member being solid and positioned in the positioning step; and a curing step of, while the sealing member melted in the melting step is in close contact with at least the upper surface of the at least one light-emitting element, heating the sealing member at a temperature equal to or higher than the secondary cross-linking temperature, the silicone resin decreasing in viscosity reversibly in a temperature region between a room temperature and the temperature lower than the secondary cross-linking temperature, and being totally cured non-reversibly in a temperature region equal to or higher than the secondary cross-linking temperature.
