摘要：
A substrate holding apparatus can meet the request for a smaller-sized compact apparatus while ensuring a sufficient immersion depth of a substrate in a processing liquid. The substrate holding apparatus includes: a substrate holder for supporting a substrate (W) by bringing a peripheral portion of a surface of the substrate (W) into contact with a first sealing member; and a substrate pressing section for lowering relative to the substrate holder so as to press the substrate (W) held by the substrate holder downward, thereby bringing a first sealing member into pressure contact with the substrate (W). The substrate pressing section is provided with a second ring-shaped sealing member which makes pressure contact with an upper surface of a ring-shaped holding section of the substrate holder, thereby sealing the peripheral region of the substrate pressing section.
