Abstract

A clad material for a battery current collector includes a pinhole due to falling off of an intermetallic compound containing Al and Ni or an intermetallic compound containing Al and Fe from an outer surface of a first layer. A clad material for a battery current collector includes a clad material obtained by bonding a first layer made of Al or an Al alloy and a second layer made of any one of Ni, a Ni alloy, Fe, and a Fe alloy by rolling. The clad material has a thickness of 50 μm or less. In the clad material, an intermetallic compound layer constituted by an intermetallic compound containing Al and Ni or an intermetallic compound containing Al and Fe, the intermetallic compound layer having a thickness of 0.1 μm or more and 1 μm or less, is formed between the first layer and the second layer.
