PROBLEM TO BE SOLVED: To provide a blow molded body which comprises ethylene-α-olefine copolymer that has a small sagging of resin upon blow molding and an excellent moldability, and which is excellent in heat resistance, is excellent in solvent resistance, and has less components that are extracted especially by solvents such as alcohol or hydrocarbon.SOLUTION: The blow molded body comprises ethylene-α-olefine copolymer that has a monomer unit based on ethylene and a monomer unit based on α-olefine having the number of carbon atoms of 3 to 20, and that has a density of 860 to 970 kg/m, a melt flow rate of 0.01 to 10 g/10 minutes, a molecular weight distribution of 4.5 to 13, an activation energy of fluidity of 40 to 100 kJ/mol, a long chain branching content measured by NMR, of 0.29 to 0.50 carbon atoms per a number of 1000 carbon atoms, and g* defined by formula (I), of 0.76 to 0.88. g*=[&eegr;]/([&eegr;]×g*) (I) |
