Disclosed are: a hydrazide compound which has a high activity on a resin having an unsaturated bond and can react with the resin stably, and which can be used as a curing agent; a process for producing the hydrazide compound; and a heat-curing agent, a resin composition and a cured article. Specifically disclosed are: a hydrazide compound which comprises a crystalline hydrazide compound having at least one hydrazide group in the molecule and a metal element capable of forming a complex with the crystalline hydrazide compound; a curing agent for a resin, which comprises the hydrazide compound; a resin composition comprising the curing agent, a resin having at least one unsaturated bond in the molecule and an epoxy resin; a cured article produced by curing the resin composition; and a process for producing a hydrazide compound, which comprises the steps of heating a crystalline hydrazide compound having at least one hydrazide group in the molecule and a metal element capable of forming a complex with the crystalline hydrazide compound to produce a mixture, carrying out an isothermal treatment of the mixture, and cooling the mixture to produce a solidified material.
