Spring member

A spring member for being provided between two pressed bodies facing each other in a first direction, the spring member comprising:

• a conductive plate and a support plate,
• wherein the conductive plate is formed of a material in which at least one of electrical conductivity and thermal conductivity thereof is higher than that of a material forming the support plate,
• the support plate is curved or bent such that an intermediate portion thereof in a second direction orthogonal to the first direction protrudes toward a second side of the spring member in the first direction,
• the conductive plate has a part positioned furthest toward a first side of the spring member in the first direction and a part positioned furthest toward the second side of the spring member in the first direction, and
• a surface of the conductive plate positioned furthest toward the first side is a first surface of the conductive plate, and a surface of the conductive plate positioned furthest toward the second side is a second surface of the conductive plate opposite to the first surface in the first direction, wherein
• the conductive plate extends along the support plate and crosses the support plate in the first direction, and
• an intermediate portion of the conductive plate in the second direction is positioned further toward the second side in the first direction than the support plate, and a portion of the conductive plate other than the intermediate portion of the conductive plate in the second direction is positioned further toward the first side in the first direction than the support plate.
