PROBLEM TO BE SOLVED: To obtain a resin for rotational molding which is excellent in ESCR and gives a rotationally molded article excellent in inner-surface smoothness and the thickness of walls corresponding to mold corners and reduced in the content of fine particles. SOLUTION: This resin is a linear ethylene/α-olefin copolymer obtained by copolymerizing ethylene with a 3-12Cα-olefin. If has a density of 0.850-0.980g/cm<3> , an Mw/Mn ratio as determined by GPC of 3 or lower, and an MFR as measured at 190 deg.C under a load of 2,160g of 2.0-50g/10min.
