Patent ID: 8448312

Claim:
A method of manufacturing packages in which an electric component can be sealed in a cavity formed between a mutually bonded plurality of substrates, comprising: a through electrode forming step for forming a through electrode which penetrates through a through electrode forming substrate out of the plurality of substrates in the thickness direction and brings the inside of the cavity and the outside of the plurality of substrates into continuity, wherein the through electrode forming step includes: a through hole forming step for forming a through hole in the through electrode forming substrate; a metallic pin arranging step for inserting a conductive metallic pin into the through hole; and a welding step for welding the through electrode forming substrate to the metallic pin by heating the through electrode forming substrate while pressing the same by a forming die from the both sides in the thickness direction, wherein a receiving portion that can receive at least one end side of the metallic pin is formed in the forming die, and the receiving portion is formed into a tapered shape having an inner diameter widening from the bottom side to the opening side.
