DEVICE FOR INSPECTING ELECTRIC CONNECTION

摘要

PROBLEM TO BE SOLVED: To provide an electric connection inspection device having micro-fine structure excellent in durability, without worsening a degree of freedom for selection of using materials in view point of restriction in a product function accompanied to aptitudes 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. SOLUTION: In this electric connection inspection device having a plural contact terminals and for contacting electrically with an inspection object to input and output signals, a coating layer having 3μor more of thickness and having a Young's modulus higher than that of a wiring base material layer is provided on a surface of the wiring base material layer positioned in a tip part of the contact terminal.
