PROBLEM TO BE SOLVED: To provide a two-pack type curable composition which is intended to solve problems caused by formulation of a plasticizer. SOLUTION: The two-pack type curable composition comprises a main component comprising a urethane prepolymer containing terminal isocyanate groups, and a curing agent component containing a polyol, a filler, a plasticizer and a curing accelerating catalyst. A polyether polyol is used as the polyol. 2-20 wt.% of a mixture of one or more kinds of compounds selected from the group consisting of≥17C paraffin hydrocarbons, polybutenes and naphthenic hydrocarbons, based on the weight of the mixture of the above main component and the curing agent component, is used instead of the plasticizer.
