Abstract:
1. An electrode cartridge which is applied to measurement of an internal stress for a film of plating, the electrode cartridge comprising: a cathode support for supporting a cathode plate in a plating liquid, said cathode support comprising a cathode main portion and a cathode connecting portion extending downwardly from the main portion, the cathode plate having a plating section, to a back surface of which a strain gauge is attached; an anode support for supporting an anode plate in the plating liquid, said anode support comprising an anode main portion and anode connecting portions each of which has a protruding portion, the anode connecting portions extending downwardly from the anode main portion; a shield plate which is disposed on the cathode connecting portion between the cathode support and the anode support; and an anode shell which is joined to the anode support for surrounding a periphery and an end portion of the anode plate in the plating liquid disposed between the anode connecting portions and a bottomless slit between the anode shell and each anode connecting portion so as to attach an anode bag to the anode shell, wherein the cathode connecting portion abuts the protruding portion to keep a constant distance between the cathode support and the anode support; wherein a through hole is made in the shield plate in such a manner that the through hole confronts the plating section and has a geometry which is reduced by a first predetermined scale factor relative to a geometry of the plating section, and wherein an opening is made in the anode shell in such a manner that the opening confronts the plating section and has a geometry which is magnified by a second predetermined scale factor relative to the geometry of the plating section.
