A primer composition comprising the following (A), (B), (C), (D), (E) and (F) components:
- (A) a saturated hydrocarbon polymer containing at least one alkenyl group per molecule,
- (B) a silane coupling agent,
- (C) a polyvalent alkoxysilane and/or a condensation product thereof,
- (D) an organoaluminum compound and/or an organotitanium compound,
- (E) a vinyl copolymer having a backbone structure substantially comprised of a vinyl copolymer chain and containing a silicon-containing group having a hydroxyl or hydrolyzable group bound to a silicon atom and capable of crosslinking by siloxane bonding terminally of its backbone chain and/or in its side chain, and (F) a hydrosilylation catalyst,
- wherein substituents on a silicon atom in the polyvalent alkoxysilane as the (C) component consist of at least one group selected from the group consisting of alkyl and alkoxy groups.
