PROBLEM TO BE SOLVED: To provide a new organopolysiloxane which can arbitrarily vary hydrolysis reactivity of alkoxysilyl groups in accordance with the intended use. SOLUTION: This organopolysiloxane, containing plural kinds of alkoxy groups in which the organic functional group and the number of carbon atoms differ, is expressed by formula: Y<SB>a</SB>R<SP>1</SP><SB>b</SB>Si(OCH<SB>3</SB>)<SB>c</SB>(OC<SB>2</SB>H<SB>5</SB>)<SB>d</SB>(OR<SP>2</SP>)<SB>e</SB>(OH)<SB>f</SB>O<SB>(4-a-b-c-d-e-f)/2</SB>, wherein Y represents a mercapto group, epoxy group, (meth)acryloxy group, alkenyl group, haloalkyl group and/or amino group-containing organic group; R<SP>1</SP>represents an unsubstituted monovalent hydrocarbon group having no aliphatic unsaturated bond; R<SP>2</SP>represents an alkyl group having 3 and/or 4 carbon atoms; 0.01≤a≤1, 0≤b<2, 0≤c≤2, 0≤d≤2, 0<e≤2, 0≤f≤1, c+d≠0, 0.1≤c+d+e≤2.5, and 2≤a+b+c+d+e+f≤3.
