Abstract: Provided are an ultraviolet absorbing agent including a compound represented by Formula (1), in which the ultraviolet absorbing agent has a maximum absorption wavelength in a wavelength range of 350 to 390 nm in an ethyl acetate solution, and a value obtained by dividing an absorbance at a wavelength of 430 nm by an absorbance at the maximum absorption wavelength is 0.01 or less, a resin composition, a cured substance, and an optical member which include the ultraviolet absorbing agent, a method of producing an ultraviolet absorbing agent, and a compound. In Formula (1), X1 and X2 each independently represent a cyano group or the like, R1 and R2 each independently represent an alkyl group or the like, and R3 and R4 each independently represent a hydrogen atom, a halogen atom, an alkyl group, an aryl group, an alkoxy group, or an aryloxy group.
