Abstract: PROBLEM TO BE SOLVED: To obtain the subject polyurethane excellent in reactivity and mechanical characteristics, by reacting an isocyanate with a polyol containing a polyether polyalcohol having a specific structural unit, molecular weight and degree of unsaturation. SOLUTION: This polyurethane is obtained by reacting an isocyanate with,2 polyol having a molecular weight of 500-1000, including at least one kind of polyether polyol (preferably, including 5-30 wt.% ethylene group, based on the total weight of all polyoxyalkylene groups and having a hydroxyl number of 10-230 mgKOH/mol and functionality of 1.9-3.0) having a molecular weight of 500-10000 g/mol, degree of unsaturation of
