A photopolymerizable composition including a cationically polymerizable compound and a cation generating agent represented by formula (1):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ Formula (1) D-L-A
wherein D represents a light absorption part that shows an absorption having an absorption coefficient of 1000 or more in a wavelength range of 300 nm or longer; A represents an active part which interacts with the light absorption part D to generate a cation when the light absorption part D is excited by light; and L represents a linking group which links the light absorption part D with the active part A.
