Abstract: A dispenser for applying creamy solder onto a substrate, comprising: a syringe 1 storing therein creamy solder; a needle 2 fixed at the forward end of this syringe 1; and a driving mechanism 3 using a pulse-controlled stepping motor and an eccentrically rotating drive motion. The driving mechanism 3 comprises: a linear guide 10 for guiding a syringe holder which holds the syringe 1, a stepping motor 11, a crank 13 and a connecting rod 14 rotatably supported on the crank and the syringe holder. When, the stepping motor 11 is rotated by a predetermined angle, the crank 13 and the connecting rod 14 are eccentrically rotated in an interlocking relation to the rotation of this stepping motor, and the syringe 1 is upwardly and downwardly moved within a predetermined range through a syringe holder 9.
