Provided is a one-component thermosetting composition in which low-temperature curability and maintenance of adhesive strength are both obtained at the same time, and low-temperature curability and moisture resistance are both obtained at the same time. Specifically, a one-component-type thermosetting resin composition is provided containing tris(3-mercaptopropyl)isocyanurate and an epoxy resin containing an epoxy compound represented by formula (1) or formula (2) or a polymer thereof. (In formula (1) and formula (2), X, X1, and X2 may be mutually the same or different and are divalent non-aromatic hydrocarbon groups including two or more –(CH2)- units in a main backbone thereof (except when X is –O-CH2-CH(-OH)-CH2-); Ar, Ar1, and Ar2 may be mutually the same or different and are divalent aromatic-containing hydrocarbon groups including divalent aromatic groups in a main backbone thereof; and n and m are each independently an integer of 1-20.) |
