PROBLEM TO BE SOLVED: To achieve miniaturization by employing a simple mechanism and to regulate a nozzle interval to an arbitrary dimension with high precision. SOLUTION: In this liquid dispenser equipped with a first guide shaft 4 and a second guide shaft 5 both of which are arranged in opposed relationship in parallel to each other, a plurality of the nozzle holders 6-13 respectively guided by the respective guide shafts and a drive means for moving the respective nozzle holders in respective axial directions while the respective nozzles 6A-13A held to the respective nozzle holders are alternately arranged with respect to the respective guide shafts, the respective nozzle holders 6-9 guided by the first guide shaft 4 are connected by a first link mechanism 15 so as not only to fix the first holder 6 to a reference position but also to respectively keep the adjacent intervals of the respective nozzle holders 6-9 the same and the respective nozzle holders 10-13 guided by the second guide shaft 5 are connected by a second link mechanism 16 for keeping the adjacent intervals of the respective nozzle holders 10-13 same as the first link mechanism and one place of the second link mechanism is controlled in its axial movement by the position control means fixed on the side opposite to the reference position.
