Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ethylene-based polymer excellent in moldability, and mechanical strength and environmental breaking stress resistance, and capable of giving a molded article excellent in appearance, especially a blow-molded article. SOLUTION: This ethylene-based polymer containing 0.02-0.50 mol% constituting unit introduced from a 6-10C α-olefin is provided by satisfying any one or more of the following (1) and (2) in its cross fractionation chromatography (CFC). (1) The amount of eluted components at ≤80°C is ≤5% based on the total eluted amount in the CFC. (2) A relational formula (Eq-1) [wherein, Sxis the total value of areas of total peaks based on the components eluted between 70-85°C; Stotalis the total value of areas of total peaks based on the components eluted between 0-145°C] is satisfied.
