A thermoplastic elastomer molded article having a surface treated with a silicone emulsion and/or aqueous solution of silicone containing water-soluble silicone with a silicone content of 1 to 30 wt % is provided. As the thermoplastic elastomer, a composition comprising 20 to 100 wt % of 1,2-polybutadiene having a 1,2-bond content of 70% or more and a degree of crystallinity of 5 to 50% and 0 to 80 wt % of other thermoplastic elastomers, provided that the total amount of the 1,2-polybutadiene and the other thermoplactic elastomers is 100 wt %, can be given. The molded article of the present invention can be applied to various types of tubes, sheets, and hoses as well as a tube for medical use since the surface of the article has improved sliding properties and sliding wear resistance, without impairing transparency, flexibility, lightweightness, and mechanical strength.
