The blocked isocyanate is a blocked isocyanate containing a latent isocyanate group, which is an isocyanate group blocked with a blocking agent, wherein the blocked isocyanate includes a first latent isocyanate group that is an isocyanate group blocked with a first blocking agent and a second latent isocyanate group that is an isocyanate group blocked with a second blocking agent; and the first blocking agent is represented by general formula (1) below, and has a higher catalysis activity that activates the isocyanate group than that of the second blocking agent. (where R1 to R3 represent a hydrocarbon group having 1 to 12 carbon atoms or a hydrogen atom, and at least one of R1 to R3 represents a hydrogen atom, and R1 and R3 may be bonded to each other to form a heterocycle. R4 represents an atomic group represented by -NR 5 R 6 (R5 and R6 represent a hydrocarbon group having 1 to 12 carbon atoms, and R5 and R1 may be bonded to each other to form a heterocycle and R6 and R3 may be bonded to each other to form a heterocycle).
