PROBLEM TO BE SOLVED: To provide a package for optical communication which has airtight reliability and reliably passes light of an optical fiber. SOLUTION: In a package 10 for optical communication which has a base body 15 made of ceramics or a metal in which a cavity 14 for mounting a semiconductor device for optical communication is formed in the inside, a through hole 20 which is formed at the side part of the base body 15 to communicate with the cavity 14, a metal fixing member 21 inserted into the through hole 20 and formed in a cylindrical shape, and a translucent member 24 provided so as to be opposed to the tip part of a optical fiber 23 in the cylinder of the metal fixing member 21, the metal fixing member 21 has a step part 22 in the cylinder, and the translucent member 24 cemented to the step part 22 is in the cylinder from the tip part of the metal fixing member 21.
