In the present invention, two heating means are provided, each having a heating surface for heating an object to be sealed, and the object to be sealed is heated from both sides thereof by both heating surfaces, which face each other. Both heating means have a convex-shaped heating part protruding in the direction of approaching the object to be sealed. Both heating means are configured so as to vary, in localized fashion, the degree of heating of the object to be sealed, so as to pre-heat appropriately for each portion of the object to be sealed. Pre-heating to a temperature suited for resin sealing is thereby performed efficiently even when the object to be sealed has a special shape or has portions having different material properties. |
