布线基板和布线基板的制造方法
摘要：
本发明涉及一种布线基板和制造布线基板的方法，该方法包含：第一步是在支承板上形成由金属制成的电极焊盘；第二步是以这样的方式蚀刻支承板，以使支承板具有包含要与电极焊盘接触的突出部分的形状；第三步是在支承板的表面上形成用来覆盖电极焊盘的绝缘层；第四步是在绝缘层的表面上形成要连接到电极焊盘上的导电图形；第五步是移除支承板。
摘要（英）：

The present invention relates to a wiring substrate and wiring substrate manufacturing method. The method of manufacturing a wiring substrate comprises: a first step of forming, on a support plate, an electrode pad made of metal; a second step of etching the support plate in such a manner that the support plate has a shape which includes a projection portion to be contacted with the electrode pad; a third step of forming, on the surface of the support plate, an insulating layer for covering the electrode pad; a fourth step of forming, on the surface of the insulating layer, a conductive pattern to be connected to the electrode pad; and, a fifth step of removing the support plate.
