A liquid transport apparatus includes a base member having a surface in which a pressure chamber and a liquid flow passage are formed, the liquid flow passage being communicated with the pressure chamber and having a flow passage cross-sectional area smaller than that of the pressure chamber and a piezoelectric actuator having a pressure-applying portion which applies a pressure to a liquid in the pressure chamber and an opening/closing portion which opens and closes the liquid flow passage. The pressure-applying portion faces the pressure chamber, the opening/closing portion faces the liquid flow passage, and the pressure-applying portion and the opening/closing portion are arranged along the surface of the base member.
