Abstract
A package member has fitted in a through hole thereof a pipe member with an optical fiber inserted therein, the optical fiber including a jacketted part thereof fitted in and soldered to an inside region of the pipe member, with a solder filled therebetween, and a stripped part thereof fitted in and fixed to another inside region of the pipe member, with an adhesive filled therebetween, while the pipe member is fixed to the package member by a welding along a circumference of the through hole, without using a fixing ring, permitting a relatively high hermeticity to be achieved in a facilitated fabrication process.
