Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a substrate treating method and a substrate treating apparatus that can improve treatment accuracy when treating substrates by discharging a treatment liquid to the substrates, and can effectively utilize the treatment liquid. SOLUTION: In the substrate treating apparatus, the discharge area of a discharge section 7a in a nozzle 7 is not changed, thus preventing a change in the flow rate of a developer Q due to a change in the discharge area, and irregularities in the development of the substrate W due to the change in the flow rate of the developer Q discharged to the substrate W. Additionally, the developer Q discharged to the substrate W from the nozzle 7 is collected by a slender collection port 22 at a collection section 15 oppositely arranged at the lower side of the discharge section 7a of the nozzle 7. As a result, the developer Q is exposed to air only while the developer Q is discharged from the discharged section 7a for reaching the collection ports 22, thus decreasing the exposure of the developer Q to air for reducing a change in the characteristics, and reusing the developer Q for effective utilization.
