Provided is a thermoresponsive material containing bubbles and has improved durability. A thermoresponsive material 1 whose state changes, depending on a change in temperature, comprises a matrix 2 in which bubbles 4 having an average diameter of 30 to 400 μm are dispersed. Satisfied is D/a≤0.7, where D represents the standard deviation of diameters of the bubbles 4, and a represents the average diameter of the bubbles 4. Satisfied is 0.3≤V1/V2≤0.9, where V1 represents the volume of the bubbles 4 at room temperature, and V2 represents the apparent volume of the matrix 2 at room temperature. The matrix 2 contains a liquid crystalline polyurethane. |
