1 - butene based polymer satisfying following requirements (1") to (4") provides formed product having low stickiness, superior flexibility and transparency. (1") Crystalline resin having melting point (Tm - P), not observed or in the range of 0 to 100 DEG C, wherein said melting point defined as the peak top of the peak observed in the highest temperature zone of the melting heat absorption curve obtained by heating a sample of said polymer at a rate of 10 DEG C/minute using Differential Scanning Calorimeter (DSC), after melting said sample in advance at 190 DEG for 5 minutes under nitrogen atmosphere, followed by cooling it to -10 DEG C at a rate of 5 DEG C/minutes, and keeping it at -10 DEG C for 5 minutes. (2") Stereoregularity index ä (mmmm) / (mmrr + rmmrü is at most 20. (3") Molecular weight distribution (Mw / Mn) measured by Gel Permeation Chromatography (GPC) method is at most 4.0. (4") Weight average molecular weight (Mw) measured by GPC method is in the range of 10,000 to 1,000,000.
