摘要：
An electrical connection member (1, 301, 401, 501, 601) includes a clad material (10, 110, 610) including at least both a first Cu layer (12) made of a Cu material and a low thermal expansion layer (11) made of an Fe material or Ni material having an average thermal expansion coefficient from room temperature to 300°C smaller than that of the first Cu layer, the first Cu layer and the low thermal expansion layer being bonded to each other.
