ELECTRICAL TEST PROBE AND ELECTRICAL TEST PROBE ASSEMBLY

摘要

An electrical test probe and an electrical test probe assembly is provided to improve durability of a probe by preventing a defect or damage of a needle part of the probe. An electrical test probe(122) includes a needle part(122b) and a needle main body part. The needle main body part includes a pedestal part which is formed by protruding the needle part. The needle main body part is made of a metal material having toughness. The needle part is formed at the needle main body part. The needle part is composed of a stacked structure of a first metal material layer(140a) and a second metal material layer(140b). The first metal material layer has hardness higher than the hardness of the metal material of the needle main body part. The second metal material layer has the toughness higher than the toughness of the first metal material layer.
