PROBLEM TO BE SOLVED: To provide an optical communication package capable of preventing the surface of a translucent member from being clouded due to condensation of volatile constituents of heat radiation grease, and an optical module using the optical communication package.SOLUTION: In an optical communication package 10, an insertion hole 18 provided at the inside of a metal fixing member 17 includes a small diameter hole 37, a large diameter hole 38 of which the diameter is larger than that of the small diameter hole 37, and the axis is the same as that of the small diameter hole 37; and a shelf 40 for fixing a translucent member 19 in the large diameter hole 38. The diameter S of the small diameter hole 37 is equal to or larger than the diameter E0 of a minimum translucent range 43 and the difference between the diameter S of the small diameter hole 37 and the diameter E0 of the minimum translucent range 43 is up to 0.3 mm. |
