Therefore, the diameter of the bubble discharge port M may increase.
- the bubbles KA are emitted from the bubble emission port M having an enlarged diameter, so that the emission of the bubbles KA from the plurality of bubble emission ports M varies, and the substrate processing apparatus.
- the processing capability of the substrate W by 100 may decrease. Therefore, the gas supply pipe 131 made of quartz has been replaced in about half a year to one year.

Therefore, the replacement life (about several years) of the treatment liquid supply pipe 167 is equal to that of the gas supply pipe 131. It is longer than the life (half a year to a year). Therefore, since the gas supply pipe 131 is replaced more frequently than the processing liquid supply pipe 167, the inventor of the present application has an object to extend the replacement life of the gas supply pipe 131.

- the inventor of the present application has discovered that the wettability (contact angle) of the surface of the gas supply pipe 131 affects the breakage of the bubbles KA discharged from the bubble discharge port M. Specifically, the inventor of the present application is able to discharge the small bubbles KA from the bubble outlet M as the wettability of the surface of the gas supply pipe 131 becomes smaller (the contact angle becomes larger) so that the bubbles KA are broken. I have found Further, the inventor of the present application has the smallest wettability of the surface of the gas supply pipe 131 made of PEEK among the various gas supply pipes, and thus the small bubbles KA are effective from the bubble discharge port M of the gas supply pipe 131 made of PEEK.
