The present invention has focused on change in elastic modulus or breaking stress when a liquid crystalline polymer transits from a liquid crystal phase to an isotropic phase due to temperature change, and provides a thermal responsive material having strength (durability) not below a certain level and an excellent responsiveness. The thermal responsive material contains, as a matrix, a liquid crystalline polymer that reversibly changes between the liquid crystal phase and the isotropic phase according to the temperature change, wherein, when the elastic modulus of the matrix when containing the liquid crystal phase is represented as E1 and the elastic modulus of the matrix when containing the isotropic phase is represented as E2, E1/E2≤1000 is satisfied, and when the breaking stress of the matrix when containing the liquid crystal phase is represented as σ1 and the breaking stress of the matrix when containing the isotropic phase is represented as σ2, σ1 /σ2≤40 is satisfied.
