WIRING BOARD AND MOUNTING STRUCTURE INCLUDING THE SAME

摘要

According to an aspect of the invention, a wiring board includes an inorganic insulating layer and a conductive layer disposed on part of one main surface of the inorganic insulating layer. The part of the one main surface of the inorganic insulating layer includes a plurality of first recessed portions each of which has at least partially circular shape in a plan view. Part of the conductive layer enters into the plurality of first recessed portions. According to the aspect of the invention, it is possible to obtain a wiring board capable of reducing disconnection of the conductive layer and therefore having superior electrical reliability.
