(2) A phase substantially not containing the cavities is formed with application of an active energy ray in the compatible state of the photopolymerizable compound and solvent. (3) After the layer is cured with the application of the active energy ray in a phase-separation state of the photopolymerizable compound and solvent, the solvent dispersed in the layer is volatilized, thereby a phase containing the hollows is formed.
