PROBLEM TO BE SOLVED: To provide a hermetic sealing method capable of suppressing the deformation of a housing or the like due to heat during hermetic sealing, to perform low-temperature hermetic sealing, in a component or an apparatus intended for optical communication having a space system, and to provide a hermetically sealed body, as well as a heating apparatus that use the method. SOLUTION: The hermetic sealing method for hermetically sealing a housing 1 and a lid 2 comprises the steps of forming wetting layers 4, 5 on a sealing region of the housing and a sealing region of the lid, respectively; disposing a low-melting material layer 3 at a part where the housing 1 contacts the lid 2; and combining the housing 1 and lid 2 to heat and pressurize the region as a whole in close vicinity to the part where the low-melting material for the housing 1 and lid 2 is disposed, to melt the low-melting material, and to braze and hermetically seal the region of the wet layers 4, 5 in an inert gas atmosphere.
