WIRING BOARD, ELECTRONIC COMPONENT DEVICE, AND METHOD FOR MANUFACTURING THOSE

摘要

A wiring board includes plural terminals, an insulating layer, and recess portions. Each terminal includes a roughened upper surface and a roughened side surface. The insulating layer is formed between the terminals. The upper surfaces of the terminals are exposed. An upper surface of the insulating layer is a concave curved surface. The recess portions are formed in the insulating layer around the terminals so as to partially expose the side surfaces of the terminals.
