PROBLEM TO BE SOLVED: To provide a wiring substrate of such a structure as wiring and its connection terminals are provided, while being exposed, on a substrate produced through dehydration condensation in which the exposed wiring and connection terminals are not stripped even if a current is carried under high temperature, high humidity environment and incomplete connection is prevented, and to provide an electric apparatus and a switch comprising it. SOLUTION: The wiring substrate 2 has wiring 8 formed on a substrate body 7 composed of polymer resin synthesized through dehydration condensation. A connection terminal 9 of the wiring 8 is formed under exposed state at least at a part of the substrate body 7 and at least the exposed part 9c of the connection terminal 9 is formed of conductive paste exhibiting water resistance produced by adding conductive particles to addition polymerization type polymer resin.
