Abstract
PURPOSE: To facilitate the formation of a minute Permalloy after conductive path formation by causing a Permalloy film having a desired form to adhere onto a high- polymer resin film formed on a sustrate.
CONSTITUTION: After an ansulating film, for example, SiO2 7 is caused to adhere onto substrate 6, heat-proof high-polymer resin, for example, PIQ (polyimide- system high-polymer resin) film 8 is caused to adhere onto SiO2 7, and conductive path film Al-Cu 9 having a desired form is caused to adhere onto film 8. Then, the second high-polymer resin film 8 is caused to adhere onto conductive path film 9 and the exposed part of resin film 8, and Permalloy film 11' having a desired form is caused to adhere onto a desired part of film 8. As a result, a minute Permalloy pattern can be performed easily after forming the conductive path.
