A substrate liquid processing apparatus of the present invention includes a guide rotary cup configured to guide a process-liquid scattering from a substrate rotating and being held by a substrate holding table and a guide cup configured to guide downward the process-liquid guided by the guide rotary cup. The guide cup includes a downward extension portion extending downward from an inner peripheral end portion of a guide cup body and an inner peripheral extension portion extending inward from the inner peripheral end portion more than the downward extension portion. The inner peripheral extension portion is configured to form a gas guide space together with the guide rotary cup and the downward extension portion so that a gas turning by the rotation of the guide rotary cup can be guided downward.
