The thermoplastic resin composition of the present invention, which is a thermoplastic resin composition containing a thermoplastic resin and a solid plasticizer, is characterized in that the solid plasticizer is at least one compound selected from the group of three kinds of compounds (i) a multiester compound of (A) (A1) an alcohol having a substituted cyclohexane ring or a substituted cyclohexene ring substituted by at least one of an alkyl group and having at least 3 carbons in the alkyl group, or (A2) an alcohol having a bridged ring containing at least one of a six-membered carbon ring with (B) a polybasic acid, (iia) a phosphorus compound having a melting point of 55 to 100°C, etc., and (iiia) a diester compound of (C) (c1) hydroquinone or lesorcinol wherein benzene ring may be substituted by an alkyl group, or (c2) catechol wherein benzene ring is substituted by an alkyl group with (D) an organic monobasic acid. Further, the thermoplastic resin composition of the present invention is high in safeness to human genital organs. The thermoplastic resin composition can be employed as a thermally- and pressure-sensitive adhesive, and there can be obtained a thermally- and pressure-sensitive adhesive sheet having an excellent blocking resistance by coating it over a base material sheet.
