A liquid treatment device is provided to suppress the bounding of mists in a processing liquid by using a rotating cup to rotate together with a substrate. A liquid treatment device includes a substrate holding portion(1), a rotating cup(3), a rotating tool, a liquid supply tool, and an exhaust and drain portion(6). The substrate holding portion(1) holds a substrate in a horizontal direction and is rotated according to a rotation of the substrate. The rotating cup(3) encloses the substrate and is rotated according to a rotation of the substrate. The rotating tool integrally rotates the rotating cup(3) and the substrate holding portion(1). The exhaust and drain portion(6) performs an exhaust and a drain of the rotating cup. The exhaust and drain portion(6) includes a drain cup for receiving a processing solution from the substrate and an exhaust cup for receiving and exhausting gas components.
