Abstract: Thermosensitive fine particles of the present invention include a side chain crystal polymer which is crystallized at a temperature lower than a melting point and which exhibits fluidity at a temperature equal to or more than the melting point. The side chain crystal polymer may include, as a monomer component, a (meth)acrylate having a straight-chain alkyl group having 14 or more carbon atoms. A mean particle diameter of the fine particles may be 0.1 to 50 μm. The thermosensitive fine particles may include no organic solvents.
