The present invention addresses the problem of providing: an acid- and radical-generating agent which has high sensitivity to an active energy ray having a wavelength of about 300 to 450 nm, can exhibit both high acid-generating ability and high radical-generating ability, and has heat resistance; and a method for producing an acid and a radical. The present invention relates to: a compound represented by general formula (A); an acid- and radical-generating agent comprising the compound; and a method for producing an acid and a radical. (In the formula, n R1's independently represent an alkyl group which may have a specific functional group in the chain and may be substituted by a halogen atom, an alkoxy group which may be substituted by a halogen atom, an aryl or aryloxy group which may be substituted by a halogen atom, an alkyl group or a haloalkyl group, or an arylalkyl or arylalkyloxy group which may be substituted by a halogen atom, an alkyl group or a haloalkyl group; n R2's and n R3's independently represent a hydrogen atom, an alkyl group or an alkoxycarbonyl group; R4 to R7 independently represent a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an alkenyl group, an aryl group, an alkoxycarbonyl group, a dialkylamino group or a nitro group; Y represents an oxygen atom, a sulfur atom or a carbonyl group; n Z's independently represent a sulfonyl group or an alkoxyphosphoryl group; and n represents 1 or 2.)
