PACKAGE FOR HOUSING OPTICAL SEMICONDUCTOR ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a package in which an optical semiconductor element is operated normally and stably for a long period by a method wherein a base which is composed of a metal and a lead terminal are bonded strongly via a sealing glass. SOLUTION: This optical semiconductor package is provided with lead terminals 3 ends on one side of which are inserted into through holes 1a in a container body 1 and which are bonded via the sealing glass 4. The sealing glass 4 is composed of a porous glass with a mean pore size of 3 to 15 μm and at a porosity of 3 to 7%.
