Claim:
1. An olefin resin satisfying the following requirements (I) to (V): (I) a melting peak (Tm) as measured by differential scanning calorimetry (DSC) is observed within the range of from 60° C. to 130° C., and the heat of fusion ΔH at the melting peak is within the range of from 5 to 150 J/g; (II) the percentage E (wt %) of a portion soluble in o-dichlorobenzene at 20° C. or lower as measured by cross-fractionation chromatography (CFC), and the heat of fusion ΔH as described in (I) above, satisfy the following relationships: (III) the glass transition temperature (Tg) as measured by differential scanning calorimetry (DSC) is within the range of −80 to −30° C.; (IV) the spin-spin relaxation time (T2) of a component having the highest mobility, as obtained in a four-component approximation by a Lorentzian function performed for a free induction decay curve obtained by Carr Purcell Meiboom Gill method in a pulsed nuclear magnetic resonance measurement (pulsed NMR) at 200° C., is within the range of from 150 to 500 ms, and the abundance ratio of the component is within the range of from 15 to 50%; and (V) the intrinsic viscosity [η] as measured in decalin at 135° C. is within the range of from 0.1 to 12 dl/g.
