Disclosed is a process for producing a blocked isocyanate compound represented by general formula (III): wherein R<1>, R<2>, Q<1>, and Q<2> are as defined in the specification, characterized by comprising reacting a pyrazole compound (I) with an ethylenically unsaturated group-containing isocyanate compound (II) at a temperature in the range of 0 DEG C to 90 DEG C. The production process can efficiently produce a high-purity blocked isocyanate compound without substantially producing by-products. In the production process, unlike the prior art technique, since there is no need to use any inert solvent such as toluene or xylene, safety to the human body and environment is excellent and the production processes and equipment can be simplified. The blocked isocyanate compound produced by the production process contains no residual inert solvent and is suitable for use in extensive fields such as various coating agents, adhesives, and molding materials.
