Patent ID: 8508099

Claim:
A package manufacturing method for manufacturing a package using a rivet having a flat plate-shaped head portion and a core portion protruding from a rear surface of the head portion, the package including a plurality of substrates in which adjacent substrates are bonded to each other in a laminated state, a cavity which is formed by being sandwiched by a pair of substrates of the plurality of substrates, and which houses an object to be housed in an airtightly sealed state, the core portion which is disposed in a through hole that penetrates a base substrate that is one of the pair of substrates, and which electrically connects the object to be housed with the outside, and a glass frit that is filled between the through hole and the core portion and is fired to form a seal between the through hole and the core portion, the package manufacturing method comprising: a rivet disposing step of inserting the core portion into the through hole until the rear surface of the head portion comes into contact with a first surface of the base substrate, and disposing the rivet in the base substrate; a glass frit filling step of filling the glass frit in a paste form between the through hole and the core portion, in the base substrate in which the rivet is disposed; and a firing step of integrally fixing the through hole, the rivet and the glass frit by firing the filled glass frit, and sealing between the through hole and the core portion; wherein a gas relief passage, which leads from a base end of the core portion to one of a side surface and a front surface of the head portion, is formed on the rear surface of the head portion of the rivet.
