1. A conductive member comprising:
- a conductive member main body portion that has Vickers hardness equal to or greater than 100Hv and is made of copper or a copper alloy; and
a film layer that is formed on an end face of the conductive member main body portion and is made of aluminum or an aluminum alloy, whereinthe film layer is formed by accelerating a powder material of aluminum or an aluminum alloy together with a gas heated to a temperature lower than a melting point of the powder material, spraying the powder material still remaining in a solid phase onto an end face of the conductive member main body portion, and causing the powder material to be deposited thereon.

Abstract
A conductive member includes: a conductive member main body portion that has Vickers hardness equal to or greater than 100Hv and is made of copper or a copper alloy; and a film layer that is formed on an end face of the conductive member main body portion and is made of aluminum or an aluminum alloy. The film layer is formed by accelerating a powder material of aluminum or an aluminum alloy together with a gas heated to a temperature lower than a melting point of the powder material, spraying the powder material still remaining in a solid phase onto an end face of the conductive member main body portion, and causing the powder material to be deposited thereon.
