Provided are: a cyanic acid ester compound which can exhibit excellent heat conductivity; a method for producing the cyanic acid ester compound; a resin composition; a cured article; a single-layer resin sheet; a laminated resin sheet; a prepreg; a metal-foil-clad laminated plate; a printed wiring board; a sealing material; a fiber-reinforced composite material; and an adhesive agent. The cyanic acid ester compound according to the present invention is represented by formula (1). In formula (1), R1, R2 and R3 independently represent a monovalent substituent and independently represent a hydrogen atom, a linear or branched alkyl group having 1 to 6 carbon atoms, or a halogen atom, wherein the case where each of R1, R2 and R3 is a hydrogen atom is excluded; and n, m and l independently represent an integer of 0 to 4.
