Classification: CPC H  B | IPC B  H

Claim 0:
1. A composite material, comprising:
a first region formed of a first metal foam layer and
a second region formed of a second metal foam layer,
wherein the first metal foam layer has a conductive metal component,
wherein the conductive metal component has a conductivity at 20° C. of 8 MS/m or more,
wherein the second metal foam layer has a soft magnetic metal component, and
wherein the metal foam layers of the first region and the second region are laminated on each other,
said composite material further comprising a conductive material-containing layer, wherein the conductive material-containing layer is on the first or second metal foam layer,
wherein the first metal foam layer and the second metal foam layer are laminated on each other in a staggered pattern such that a portion of a surface of the first metal foam layer facing the second metal foam layer does not overlap with a surface of the second metal foam layer facing the first metal foam layer, and/or a portion of the surface of the second metal foam layer facing the first metal foam layer does not overlap with the surface of the first metal foam layer facing the second metal foam layer, and
the conductive material-containing layer is formed on the portion of the surface of the first metal foam layer facing the second metal foam layer which does not overlap with the surface of the second metal foam layer facing the first metal foam layer, or the portion of the surface of the second metal foam layer facing the first metal foam layer which does not overlap with the surface of the first metal foam layer facing the second metal foam layer.
