Abstract: Provided is a composite member, including: an inorganic layer that contains an inorganic substance containing at least one of a metal oxide or a metal oxide hydroxide. The composite member includes a resin layer that is provided on a surface of the inorganic layer and contains a resin and inorganic particles that are dispersed in the resin and some of which adhere directly to the inorganic substance of the inorganic layer. A porosity in a cross section of the inorganic layer is 20% or less, and a peak derived from a hydroxyl group is detected for the inorganic layer when measurement is performed using infrared spectroscopy or X-ray diffraction.

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.
