PROBLEM TO BE SOLVED: To provide a method of manufacturing a package for optical communication by which a light-transmissive member is easily and securely joined to a refraction part of a metallic fixation member. SOLUTION: The method of manufacturing the package 10 for optical communication is for forming a through hole 19 communicating with a cavity part 14 in a frame body 14, joining the metallic fixation member 20 having the refraction part 23 in its insertion hole 21 to the through hole 19, and joining the light-transmissive member 22 to the refraction part 23. The method includes: a process of forming a small- diameter hole 26 having a first axis 25 on the one side of the insertion hole 21 and a large-diameter hole 28 having a second axis with an angle to the first axis 25 on the other side and mounting the light-transmissive member 22 on a step part 29 where the small-diameter hole 26 changes to the large-diameter hole 28; a process of preparing a fixture 33 for joining in which the shape of the surface of the connection part between a block body 31 and a press body 32 is formed of a convex spherical surface and a concave spherical surface or a convex spherical surface and a reversely conic surface; and a process of weighting the light-transmission member 22 with the press body 32 and heating and joining the light-transmissive member 22 to the step part 29 while pressing the member 22 by the block body 31.
