PROBLEM TO BE SOLVED: To provide an organopolysiloxane excellent in drawing property and further in solubility/dispersibility to water or lower alcohol. SOLUTION: The organopolysiloxane comprises a poly(N-acylalkyleneimine) segment composed of a repetitive unit represented by the general formula (1) (wherein R<SP>1</SP>represents hydrogen atom or 1-22C alkyl group, aralkyl group or aryl group, and n represents 2 or 3) bonded to at least two of silicon atoms of an organopolysiloxane segment constituting the main chain through an alkylene group containing hetero atom. The mass ratio of the organopolysiloxane constituting the main chain to the poly(N-acylalkyleneimine) segment is 65/35-82/18, and the weight average molecular weight of the organopolysiloxane segment constituting the main chain is 10,000-100,000.
