Disclosed is a drum washing machine capable of enhancing precision for detecting a load quantity. The drum washing machine includes: an outer tank (20), configured in a shell (10); a drum (22), configured in the outer tank (20) and capable of rotating by using a horizontal shaft or an inclination shaft inclining relative to a horizontal direction as a center; a rotating body (24), configured at a rear part of the drum (22) and having protruding parts (24a) in contact with washings on a surface of the rotating body (24); a driving part (30), capable of operating in a first drying form and a second driving form, wherein the first driving form refers to a driving form which enables the drum (22) and the rotating body (24) to rotate at different rotating speeds, and the second driving form refers to a driving form which enables the drum (22) and the rotating body (24) to rotate integrally at the same rotating speed; and a control part (801). Herein, the control part (801) enables the driving part (30) to operate in a biaxial driving form so that the drum (22) accelerates to rotate to an attaching speed at which washings can be attached to an inner circumferential surface of the drum (22), and detects the load quantity of washings in the drum (22) according to a rotating load applied to the drum (22) and the rotating body (24) that rotates relative to the drum (22) when the drum (22) accelerates to rotate to the attaching speed (S11 and S12).
