摘要： An α-olefin oligomer having the following features (1) to (6), and a method for producing the α-olefin oligomer using a particular double-crosslinked meso complex provide an α-olefin oligomer that contains a smaller amount of a dimer component while having a low viscosity, not in accordance with the Schulz-Flory distribution, and a method for producing the same:
(1) a trimer component proportion C3 (% by mass) that is larger than a theoretical value obtained from the S-F distribution,
(2) a hexamer component proportion C6 (% by mass) that is smaller than a theoretical value obtained from the S-F distribution,
(3) a kinematic viscosity at 100°C of 20 mm 2 /s or less,
(4) a meso triad fraction [mm] measured by 13 C-NMR of 40% by mol of less,

(6) an average carbon number of a monomer unit of from 6 to 30,

wherein the S-F distribution is calculated based on a chain propagation probability α calculated from a dimer component proportion C2 (% by mass).
