Abstract
A film material according to the present disclosure includes an amorphous polymer (A) including a reversible bond which is reversibly dissociated and recombined in response to a temperature change. The polymer (A) has a glass transition temperature of higher than or equal to 40° C. The polymer (A) has a storage elastic modulus of greater than or equal to 0.2 MPa at a temperature higher than the glass transition temperature by 100° C. and a storage elastic modulus of less than or equal to 100 MPa at a temperature higher than the glass transition temperature by 50° C.
