DEVICE FOR INSPECTING ELECTRIC CONNECTION

摘要

PURPOSE: To provide an electric connection inspection device having micro-fine structure excellent in durability, to which an electrode material is hardly deposited and flocculated, without worsening a degree of freedom for selection of using materials in view point of restriction in a product function accompanied to aplitudes of an electric characteristic such as an electric resistance and a physical property such as an internal stress, and restriction in production such as the propriety of using a plating method. CONSTITUTION: In this electric connection inspection device having a plurality of contact terminals and for contacting electrically with an inspection object to input and output signals, a coating film of the second layer having 1x10¬-4 Ωcm or less of specific resistance and having a Young's modulus higher than that of a wiring base material layer is formed on a surface of the wiring base material layer positioned in a tip part of the contact terminal, and a coating film of the third layer having a low flocculating property is formed further on a surface of the second layer.
