Abstract
A liquid processing apparatus includes a first line to which a processing liquid pressurized by a pump is sent from a processing liquid supply source; a plurality of second lines into which the pressurized processing liquid flowing through the first line flows; a branch line connected to a branch point on each of the second lines; a liquid processing unit configured to process a substrate with the processing liquid; an orifice provided at an upstream side of the branch point; and a first control valve provided at a downstream side of the branch point. The first control valve changes an amount of the processing liquid flowing to a downstream side of the first control valve to control a pressure of the processing liquid in a section between the orifice of the second line and the first control valve, and to control a flow rate of the processing liquid.
