1. An anode for a lithium secondary battery, wherein an anode material layer is disposed on at least one surface of an anode current collector, and the anode material layer comprises large-particle graphite, a small-particle silicon-based material, and fine-particle graphite, and satisfies the following conditions 1 to 3:
condition 1: a diameter D50 of the large-particle graphite (D1) is 1 to 50 μm;
condition 2: a diameter D50 of the small-particle silicon-based material (D2) is 0.155D1 to 0.414D1; and
condition 3: a diameter D50 of the fine-particle graphite (D3) is 0.155D1 to 0.414D1, or 0.155D2 to 0.414D2.
