A film-like structural color body comprises a front surface layer disposed on a front surface side, a back surface layer disposed on a back surface side, and an intermediate layer disposed between the front surface layer and the back surface layer, the front surface layer, the back surface layer and the intermediate layer contain block copolymers and have micro-phase separated structures including lamellar micro domains, each of the micro domains has a wave-like shape having amplitudes in the thickness direction of the structural color body, a maximum value of predetermined distances in the micro domains of the front surface layer and a maximum value of predetermined distances in the micro domains of the back surface layer are larger than the wavelength in the visible light range, and predetermined distances in the micro domains of the intermediate layer are equal to or less than the wavelength in the visible light range. |
