Abstract:
1. A wiring board comprising: terminal members put on terminal pads of a multilayer board made by alternately stacking one or more conductor layers and one or more resin insulation layers, wherein a solder resist layer configured to cover the multilayer board is formed on a surface, on which the terminal pads are formed, of the multilayer board, the solder resist layer is provided with terminal openings at positions corresponding to the terminal pads, and each of the terminal members is a pin member including a base whose bottom surface is bonded to each of the terminal pads inside the terminal openings by way of solder and a pin that stands upright on a top surface of the base; and an electric insulation surface layer made of an electric insulation material formed over an exposed surface of the solder to which the base is bonded, wherein the solder is bonded to the bottom surface of each of the bases and the solder is not bonded to the top surface of each of the bases, the electric insulation surface layer is not bonded to the top surface of each of the bases, and the electric insulation surface layer is not bonded to an area of the solder resist layer between the terminal openings.
