A microcapsule that comprises, as a shell material for a shell encapsulating a core therein, a polyurethane or polyurea having a structure derived from a tri- or higher functional isocyanate compound together with a structure derived from a bifunctional aliphatic isocyanate compound and/or a structure derived from a bifunctional aromatic isocyanate compound, wherein: in the shell material, the ratio by mass of the content of the structure moiety derived from the bifunctional isocyanate compound(s) to the content of the structure moiety derived from the trifunctional isocyanate compound is from 5/95 to 20/80; a perfume is contained as a core material; and the break deformation rate is 50% or less, and a microcapsule-containing composition. |
