PROBLEM TO BE SOLVED: To provide an aluminum chelating agent-based latent curing agent capable of curing a thermosetting epoxy resin under a condition of a relatively low temperature and a short time, and to provide a manufacturing method thereof capable of relatively easily controlling the curing conditions of aluminum chelating agent-based latent curing agent. SOLUTION: The latent curing agent has a structure where the aluminum chelating agent is held in a porous resin obtained by interfacial polymerization of a polyfunctional isocyanate compound. Preferably, the aluminum chelating agent is a complex compound where aβ-ketoenolate anion as a ligand coordinates to aluminum. The latent curing agent is manufactured by dissolving the aluminum chelating agent and the polyfunctional isocyanate compound in a volatile organic solvent, putting the thus-obtained solution into an aqueous phase containing a dispersant, and stirring under heating it to cause interfacial polymerization.
