Abstract: A liquid treating apparatus includes an etchant discharging nozzle for discharging a treating solution (E) onto an upper surface of a film carrier tape for mounting an electronic component (T) from above and a treating solution contact prevention chamber disposed on an upstream side of a liquid treating start position (A) in which an etchant (E) discharged onto an upper surface of the film carrier tape (T) through an etchant discharging nozzle starts etching and serving to prevent the discharged solution from coming in contact with the film carrier tape (T) before the liquid treating start position (A). The apparatus also includes a liquid sealing lip member of a first infiltration preventing member and an upper lip component and a lower lip component of a second infiltration preventing member disposed in the treating solution contact prevention chamber.
