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.

摘要： A cladding material for a lead capable of inhibiting foreign matter from remaining on a surface can be obtained. The cladding material (1) is a cladding material for a lead welded to a terminal (21, 22) of a battery (2) and comprises a first Ni layer (11) arranged on a side welded to the terminal of said battery, a second Ni layer (12) arranged on a side opposite to said welded side and an Fe layer (10) arranged to be held between said first Ni layer and said second Ni layer. The thickness of the first Ni layer is at least 2.1 % and not more than 8.2 % of the thickness of said cladding material consisting of the first Ni layer, the second Ni layer and the Fe layer.
