CONDUCTIVE BASE MATERIAL WITH THIN FILM RESISTANCE LAYER, METHOD OF PRODUCTION OF CONDUCTIVE BASE MATERIAL WITH THIN FILM RESISTANCE LAYER, AND CIRCUIT BOARD WITH THIN FILM RESISTANCE LAYER

摘要

An inexpensive conductive base material with a thin film resistance layer having small variation of the sheet resistance value and a conductive base material with a resistance layer enabling production of a printed resistor circuit board by stably leaving behind resistance elements, that is, a conductive base material with a thin film resistance layer comprised of a conductive base material having a resistance layer formed on its surface wherein the resistance layer includes Ni containing P and an amorphous and a crystalloid form are mixed together and a conductive base material with a thin film resistance layer comprised of a conductive base material having a resistance layer formed on its surface wherein the resistance layer is a crystalline thin film resistance layer including Ni containing P.
