Abstract
A composite including a metal member and a resin mold formed jointed to a surface of the metal member is provided, wherein the metal member has a roughened portion in a joint to the resin mold in the surface, and in a specific interface region including a joint interface between the roughened portion and the resin mold, the average volume in a unit area of voids between the roughened portion and the resin mold is 0.05 μm3 or smaller per 1 μm2 of a plane generally parallel to the joint interface, and the maximum dimension of the void is 1000 nm or smaller.

A composite comprising a metal member and a resin mold formed jointed to a surface of the metal member, wherein
- the metal member has a roughened portion in a joint to the resin mold in the surface, and
- in a specific interface region including a joint interface between the roughened portion and the resin mold,
- an average volume in a unit area of a void between the roughened portion and the resin mold is 0.05 μm3 or smaller per 1 μm2 of a plane generally parallel to the joint interface, and
- a maximum dimension of the void is 1000 nm or smaller.
A metal member comprising a roughened portion for jointing to a resin mold in a part of a surface to form a composite, wherein
- when the resin mold is jointed to the surface of the metal member in a manner such that the resin mold includes the roughened portion,
- in a specific interface region including a joint interface between the roughened portion and the resin mold,
- an average volume in a unit area of voids between the roughened portion and the resin mold is 0.05 μm3 or smaller per 1 μm2 of a plane generally parallel to the joint interface, and a maximum dimension of the void is 1000 nm or smaller.
