A fluid nozzle includes a nozzle chip that includes a through hole having an inlet port from which a fluid supplied to the fluid nozzle is introduced and an outlet port from which the introduced fluid is ejected; and a base metal member that supports the nozzle chip embedded in a rear portion of the base metal member. The fluid nozzle receives the fluid supplied to the rear portion from the inlet port and ejects the fluid from the outlet port. An exposed portion of the base metal member is covered with a ceramic coating so that the base metal member does not touch the fluid.
