PROBLEM TO BE SOLVED: To provide a metal-resin composite material applicable even to a structural member of a closed cross section or a three-dimensional shape, having high rigidity with a metal and a resin firmly joined to each other, while maintaining a strength.SOLUTION: A metal-resin composite material 1 includes, on a surface thereof: a metallic component 3 having a plurality of recesses 31 whose depth is smaller than a fiber length of a metallic fiber 4; and a resin layer 2 laminated on the metallic component 3 by injecting a resin including metallic fibers 4 with a fiber diameter of 2-30 μm and a fiber length of 1-5 mm dispersed therein. The metal-resin composite material 1 includes an engaging part 32 in which a tip end being one end the metallic fiber 4 enters a recess 31 with the resin and in which a protruding end being the other end metallic fiber 4 protrudes to the resin layer 2.SELECTED DRAWING: Figure 1 |
