SOLDERING PART OF ENDOSCOPE MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a soldering part of a high-quality endoscope member capable of soldering only the irreducibly minimum area and obtaining stable original joining strength. SOLUTION: In the soldering part of the endoscope member where the surrounding of the soldering surface 5 of a metallic part 3 to be joined to another metallic member 2 by soldering is a surface 6 which has to be prevented from being soldered, the surface 5 of the part 3 is formed by projecting the surface 5 from the surface 6 which has to be prevented from being soldered.
