摘要

PPROBLEM TO BE SOLVED: To provide a fixing part by brazing for a pipe component of an endoscope for efficiently connecting and fixing metal components by performing the brazing using a ring brazing filler metal without using any tools or the like to support the metal components. PSOLUTION: The fixing part by brazing for the pipe component of the endoscope is achieved by disposing the ring brazing filler metal 13 made by forming a brazing filler metal used for brazing into an annular shape along the peripheral surface of a first metal component 11, and by fixing by performing the brazing on the first metal component 11 and a second metal part 12 through melting the filler metal 13 by heat. A ring brazing filler metal placement surface 15 for realizing a state to place the filler metal 13 when the first and second metal components 11, 12 are assembled to be ready to fix by brazing and are disposed in a direction to be placed on a plane surface stably is formed on the second metal component 12.
