<p><P>PROBLEM TO BE SOLVED: To provide a passive element-contained wiring board and its manufacturing method which has an insulation layer, a conductor circuit pattern provided on the insulation layer, and a resistance element composed of resistance element electrodes and a resistance body forming a part of the conductor circuit pattern, wherein the shape of the resistance body is easily designed and the resistance value variation after forming is a little. <P>SOLUTION: The passive element-contained wiring board has a resistance element. At least one resistance body of the element is connected to resistance element electrodes only at their end faces. The resistance element manufacturing method comprises at least a step of forming openings in a resist layer so as to expose only the end face of the resistance element electrodes of a part of the conductor circuit pattern as a part for providing the resistance body, a step of filling a resistance paste in the resist layer openings, and a step of removing the resistance paste extruded over the thickness of the resist layer. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
