Claim Text:
1. A method of manufacturing a light-emitting device comprising a light-emitting element mounted on a substrate and sealed with a glass, the method comprising: heating the glass by a thermal conduction from a first mold that is heated to a temperature higher than a yield point of the glass, the glass contacting the first mold; heating the substrate mounting the light-emitting element and held by a second mold by a thermal conduction from the second mold, the first mold and the second mold being separated from each other when heated; and pressing the glass against the light-emitting element mounted on the substrate supported by the second mold while heating the glass to the temperature higher than the yield point of the glass to seal the light-emitting element with the glass, wherein the glass is heated off and opposite the substrate while being held by the first mold before the pressing of the glass, wherein a bottom surface of an upper one of the first mold and the second mold is provided with a locking portion for holding the substrate or the glass, and wherein the locking portion includes a first locking claw and a second locking claw which extend along two opposite sides of the substrate so as to hold the edges of the two sides of the substrate.
