As tube-phragm pump includes a pump head (1) and an electromagnetic driver (2). The pump head (1) includes a cylinder (21) having a cylindrical space formed therein, and a cylindrical flexible tube (22) arranged coaxially within the cylindrical space of the cylinder (21). The outer space between the tube and the cylinder defines an actuator fluid space to be filled with an actuator fluid, and the inner space within the tube defines a pump chamber for conveying an object fluid. The pump head also includes an intake valve (31) attached to one end portion of the flexible tube (22) and a discharge valve (42) arranged at the other end portion of the flexible tube (22). The electromagnetic driver (2) includes a plunger (71) arranged reciprocally movable in the axial direction, an electromagnet for periodically attracting the plunger (71) to drive it in the axial direction reciprocally, and diaphragm (52).
