Patent ID: 8777498

Claim:
A method for manufacturing an optical module including an optical fiber and an optical fiber insertion pipe into which an optical fiber is inserted, the method comprising: a sealing step in which the optical fiber insertion pipe is hermetically sealed, the sealing step including: a contact step in which a heat conductor member is provided along and in contact with an outside surface of the optical fiber insertion pipe, the heat conductor member having a heat conductivity greater than that of an environmental atmosphere of the sealing step and having a heat generating property of generating heat by induction heating, which heat generating property of the heat conductor member is inferior to that of the optical fiber insertion pipe in terms of heat generation amount; a heating step in which the optical fiber insertion pipe, to which the heat conductor member is thus provided in the contact step, is heated by induction heating, and a feeding step in which a solder is fed to a feed hole provided in the optical fiber insertion pipe, wherein the solder is melted by heat from the optical fiber insertion pipe, spreads into the optical fiber insertion pipe and, upon solidifying, hermetically seals the optical fiber insertion pipe.
