PROBLEM TO BE SOLVED: To provide a molded product containing 1,2-polybutadiene, excellent in a balance between flexibility and hardness, and having improved scratch resistance, and to provide a method for a surface treatment of the molded product. SOLUTION: This molded product containing 1,2-polybutadiene is obtained by irradiating the surface of a molded product containing 1,2-polybutadiene having >=70% vinyl linkage content and >=5% crystallinity and is characterized by having 99-101 hardness based on 100 hardness before the irradiation and >=30 g measured result of the scratch resistance test using Taber scratch.
