PROBLEM TO BE SOLVED: To provide an epoxy resin curing agent and a one-component type epoxy resin composition, making compatible both low-temperature curability and storage stability, and an epoxy resin cured product. SOLUTION: This micro-capsule type latent curing agent for an epoxy resin has a core and a capsule for coating the core, the core contains an amine adduct, the capsule contains a compound having an isocyanate and an active hydrogen group and/or a reaction product with water, at least one part of the reaction product is coupled with the core by a reaction with the amine adduct, and the capsule is treated by a compound having at least one functional group, so as to obtain the microcapsule type potential curing agent for the epoxy resin.
