Abstract:
1. An electrical circuit board comprising: X wiring lines and Y segmented wiring lines, each of the wiring lines being formed of a same conductive metal film and in a same plane on an insulating substrate and the Y segmented wiring lines intersecting the X wiring lines and being severed at the intersections with the X wiring lines, and spaced apart from the X wiring lines; wherein top and side surfaces of the X wiring lines are covered with an insulating film; segments of each of the Y segmented wiring lines are electrically connected together by a Y segmented wiring line-connecting electrode formed on the insulating film, the Y segments being spaced apart by the X wiring lines and the covering insulating film; wherein the insulating film covering the side surfaces of the X wiring lines is an insulating metal oxide film formed by oxidizing the side surfaces of the X wiring lines.
