Abstract: PURPOSE:To contrive both reduction in abnormal deposition and improvement in dimensional accuracy of an electrode terminal by a method wherein the necessary part only of the band-like ceramic substrate, on which a conductive metal layer is formed using a non-electrolytic plating methods, is masked with a resist, and an unnecessary conductive metal layer is removed by dissolution using an etching method. CONSTITUTION:A metal conductive layer is deposited on the whole surface of a ceramic substrate 1 which is cut into band-like form and arranged in such a manner that resistor layers 3 are arranged in a column. Then, a pair of opposingly positioned both ends only of the ceramic insulated substrate 1, which is connected to an electrode terminal layer 2 to be used for connection, is coated with a resist 7, the exposed conductive metal layer 6 of unnecessary part is removed by dissolution using an etching method, and an external electrode layer is formed. As a result, the loss in number of formed chip resistors on the multichip the substrate 1 becomes nil. Also, there is no damage on the resist 7, the abnormal deposition due to non-electrolytic plating of unnecessary part of the conductive metal layer 6 becomes nil, and the yield of the chip resistors can be improved.
