    Abstract: The invention provides a production method capable of forming a thin film resistance element having a thickness and a shape controlled in a high accuracy in a printed circuit board (core material). The production method of a thin film resistance element formed on a printed circuit board, has the steps of forming a thin film resistance layer having a predetermined thickness on the printed circuit board through an insulation layer by a dry process used in producing a semiconductor, forming an electrically conductive layer on the thin resistance layer, and etching the electrically conductive layer selectively so as to make, at least, a pair of electrically conductive pads, resulting in the thin film resistance element having a predetermined value of resistivity between the pair of electrically conductive pads. Thereby, it is possible to form the thin film resistance element having a thickness and a shape controlled in a high accuracy on the printed circuit board (core material).
