Disclosed is an (acrylic rubber)-metal complex comprising an iron-based metal treated with iron phosphate, and an adhesive layer and an acrylic rubber layer both laminated on the surface of the iron-based metal in this order, wherein the adhesive layer comprises a phenolic resin and a metal oxide and preferably further comprises a halogenated polymer. In the (acrylic rubber)-metal complex, the metal surface is treated with iron phosphate previously. Therefore, when the metal is adhered to the acrylic rubber, excellent initial adhesion and water resistance can be achieved. Further, unlike the treatment with zinc phosphate, the roughness of the surface is not observed after the treatment, and the surface roughness (Ra) (in accordance with JIS B 0601 (1994)) of the steel sheet after the treatment is 0.6 or less. Therefore, it becomes possible to reduce the abrasion against a material which contacts with a part where the rubber is uncured. |
