PROBLEM TO BE SOLVED: To provide a hydrosilylation catalyst being a platinum-vinylalkoxy silane complex which has high hydrosilylation activity and excellent preservation stability and can contribute to the reduction of the amount of platinum to be used in a hydrosilylation curing reaction in a silicone industry. SOLUTION: The hydrosilylation catalyst is the platinum-vinylalkoxy silane complex in which the vinylalkoxy silane shown by general formula (1): CH<SB>2</SB>=CH-SiR<SP>1</SP><SB>a</SB>(OR<SP>2</SP>)<SB>3-a</SB>(wherein R<SP>1</SP>and R<SP>2</SP>can be made different from each other and are each a monovalent hydrocarbon group having no aliphatic unsaturated bond; and a is 0, 1 or 2) is coordinated to a platinum atom.
