Patent ID: 7226219

Claim:
A high-frequency signal transmitting optical module, comprising: a semiconductor optical device having a semiconductor optical element; a metal can package accommodating said semiconductor optical element therein; and signal transmission pins protruding via through holes provided in a stem of said metal can package; and outer leads attached to a rear surface of said stem and extending along said signal transmission pins on both sides of said respective signal transmission pins, wherein, each of said outer leads has a fixing portion provided by bending an end portion of said each outer lead, said fixing portion being fixed to the rear surface of said stem, and wherein at the parts where the stem-side end portions of said each outer leads are bent, weakened portions to ease bending are formed, said weakened portions being arranged such that a straight line connecting the centers of said weakened portions of said respective outer leads is made in contact with the side surfaces of said signal transmission pins when the stem-side end portions of said respective outer leads are bent.
