Abstract
There is provided a method for producing a metal/ceramic bonding article wherein a metal member 12 is formed so as to have a predetermined shape by printing a resist 14 in a predetermined region on the metal member 12 to etch the metal member 12 after bonding the metal member 12 to a ceramic member 10. In this method, at least one strip-like non-printed portion 16 having a width of, e.g. 0.01 to 0.5 mm, in which the resist is not printed, is provided in a region inwardly spaced from the outer periphery of the resist 14 by a predetermined distance, e.g. 0.01 to 0.5 mm, to control the etch rate in the outer peripheral portion of the metal member 12. Thus, the width and thickness of a fillet is freely changed. For example, a stepped portion (or a stepped portion and fillet) having a width of 0.05 to 0.5 mm and a thickness of 0.005 to 0.25 mm is formed in the outer peripheral portion of the metal member 12.
