食され##h−発生し、外観上の品質が悪く実用化でき
ないという問題点を有してい友。However, conventional three-layer clad dials are formed by laminating three layers, press punching, etc.
Electromagnetic soft iron is always exposed on the surface, and anti-corrosion plating such as electroless nickel plating must be applied to it, but it is extremely difficult to completely eliminate pinholes in the plating.
It is difficult to eliminate the pinhole completely, and if there is a pinhole, electromagnetic soft iron, which has a galvanic series lower than that of copper alloy, is sacrificed 11! The problem is that it becomes ffl, corrodes, and has a poor appearance quality that makes it impossible to put it into practical use.
そこで、本発明は従来のこのような問題点を解決するた

文字板を得ることを目的としている。Therefore, in order to solve these conventional problems, the present invention is made by forming fc2F! The objective is to obtain a magnetically shielded dial plate in which high magnetic permeability materials such as electromagnetic soft iron are never exposed on the surface, and rust does not occur even without anticorrosive plating.
