PROBLEM TO BE SOLVED: To obtain the subject composition capable of remarkably controlling the generation of formaldehyde and useful for producing molds, etc., by including a thermosetting resin with a specific compound. SOLUTION: This thermosetting resin composition is obtained by including (A) a thermosetting resin containing formaldehyde (preferably a phenolic resin, a urea resin, a melamine resin, etc.), with (B) at least one compound selected from a compound of formula I [X is O or S; R1-R4 are each H, a 1-8C (substituted) alkyl, a 3-8C (substituted) cycloalkyl or the like] and a compound of formula II [R5-R9 are each H, a 1-8C (substituted) alkyl, a 3-8C (substituted) cycloalkyl or the like] (for example, hydrazodicarbonamide) in an amount of 0.1-10 wt.%.
