PROBLEM TO BE SOLVED: To allow no gap between a coaxial connector provided in a through- hole on the sidewall of an optical package and a coaxial cable connected to the coaxial connector from outside, so that the problem of poor connection with the outer-peripheral conductor of the coaxial cable is dissolved for reduced transmission loss of high-frequency signal, resulting in smooth propagation. SOLUTION: A sealing material insertion 2b, whose diameter expands toward the outside surface of a sidewall 2, is provided to the outside surface of the sidewall 2 of a through-hole 2a. A conductive elastic member 10 is so provided in the sealing material insertion 2b, as to be almost flush with the outside surface of the sidewall 2 and the end of a coaxial connector 3. |
