METAL MEMBER, METHOD FOR PRODUCING METAL MEMBER, METAL-RESIN BONDED BODY AND METHOD FOR PRODUCING METAL-RESIN BONDED BODY
FIG8 is a cross-sectional view of a metal-resin joined body according to an embodiment of the invention
Next, a metal-resin joined body 20 of an embodiment of the invention will be explained on the basis of FIG8. The synthetic resin substrate 22 is joined to the oxide film 14 formed on the surface of the metal substrate 12 by thermal compression, and constitutes the metal-resin joined body 20 shown in FIG8. Next, a method for producing a metal-resin joined body 20 as shown in FIG8 will be explained.

['1. A metal member, comprising a metal substrate formed from a metal; and an oxide film formed on a surface of the metal substrate by melting of the surface of the metal substrate, wherein a joining strength of the oxide film to the metal substrate is 45 MPa or higher as measured by the following method in which a specimen of type A as defined in ISO 19095-2 is produced by joining a PPS resin to the oxide film, and a tensile strength measured according to ISO 19095-3 for the specimen thus produced is designated as the joining strength of the oxide film to the metal substrate.', '10. A metal-resin joined body, comprising a metal substrate formed from a metal; the oxide film formed on a surface of the metal substrate; and a synthetic resin substrate formed from a synthetic resin, the synthetic resin substrate being joined to the oxide film, wherein the oxide film includes a plurality of molten parts formed by localized melting of the surface of the metal substrate and a plurality of peripheral parts formed around the molten parts by a metal scattered from the molten parts, the plurality of molten parts is provided on the surface of the metal substrate at shifted positions, and the peripheral parts formed around the adjacent molten parts overlap at least partially with one another.']
