<p><P>PROBLEM TO BE SOLVED: To obtain stable resistance value, realizes manufacture with less number of steps, and reduce environmental load without use of chromium acid in the manufacturing method of a sheet-like resistance component. <P>SOLUTION: The manufacturing method comprises a step of partially exposing a resistance thin film 2 of the Cr system by etching, with an alkali etching method, a pattern of Cu electrode of a copper clad resistance film which is formed on a resin film 1, by laminating a resistance thin film 2 of Cr system and a Cu electrode; and a step of washing, using an acid, the front surface of the exposed resistance thin film 2 of the Cr system. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
