PROBLEM TO BE SOLVED: To provide a heat-curable composition excellent in storage stability.SOLUTION: The heat-curable composition contains: at least one terminal isocyanate-containing urethane prepolymer obtained by reacting a polyisocyanate compound with a polyol compound; and a coated amine obtained by coating a solid amine having a melting point of 50°C or higher with a filler. The ratio (major axis/particle thickness) of the major axis of the filler to the particle thickness of the filler is 4 to 100 inclusive, and the particle thickness is 0.01 to 1 μm inclusive. |
