<p>PROBLEM TO BE SOLVED: To have a semiconductor element normally and stably operate for a long period of time by securing reliable continuity through improvement in the tensile strength of a lead wire of a Peltier element and assuring rigid joint between the lead wire of Peltier element and a metallized wiring layer of an input/output terminal. SOLUTION: A connecting portion of the input/output terminal 3 is provided to a flat plate through the upper and lower surface from a metallized wiring layer 11 located at the internal side of a frame 2, a metallized layer is formed at the internal surface of a cut-away portion 3d in which a stepped portion providing a small internal size is formed to the internal side from the opening in the upper surface side, and a lead wire 13 is inserted to the cut-away portion 3d and is brazed thereto for connection.</p> |
