Abstract
A current collector for a lithium ion battery includes a first conductive resin layer and a second conductive resin layer. The first conductive resin layer includes a first conductive filler. The second conductive resin layer is formed on the first conductive resin layer and includes a second conductive filler. The first conductive filler is a conductive carbon. The second conductive filler contains at least one kind of metal element selected from the group consisting of platinum, gold, silver, copper, nickel, and titanium. A volume % of the second conductive filler in the second conductive resin layer on a first surface side, which is a first conductive resin layer side, is higher than that on the second surface side that is opposite to the first conductive resin layer.
