Above a substrate holder 1, an ordinary fluid jet nozzle 2 which is capable of injecting drops of a solution having ordinary particle diameters, a fine fluid jet nozzle 3 which is capable of injecting drops of a solution having fine particle diameters which are smaller than the ordinary particle diameters, and a regular reflection laser displacement gauge 4 are disposed. These are attached on the same plate, thereby forming a head 10. The head 10 freely moves in directions X, Y and Z, as an X-axis drive portion 41, Y-axis drive portions 42 and 43 and a Z-axis drive portion 44 operate in accordance with operation commands received from a controller 50 which controls the apparatus as a whole. It is therefore possible to set the head 10 to a predetermined position on a substrate S which is held by the substrate holder 1. Thus, the respective nozzles supply the solutions to any desired positions the substrate S.
