PROBLEM TO BE SOLVED: To provide a dispensing head capable of keeping pitches of a nozzle accurately at approximately equal intervals. SOLUTION: This dispensing head 100 has at least two nozzles for dispensing liquid, and a horizontally-driving means 5 for moving each nozzle 2 mutually so as to be brought close or separated. The dispensing head 100 is provided on a dispensing device capable of dispensing the liquid simultaneously into at least two spots. The horizontally-driving means 5 is equipped with a ball screw mechanism having at least two ball screws 63, 63 disposed approximately in parallel with a nozzle 2 row, and a nozzle vertically-driving unit 4 screwed with either ball screw 63 and fixed to either nozzle 2. The horizontally-driving means 5 moves the nozzle 2 arranged on the right side from the center C1 of the nozzle 2 row and the nozzle 2 arranged on the left side from the center C1 respectively in the reverse directions along the nozzle 2 row by the ball screw mechanism.
