To provide a dispenser needle installed in a dispenser device capable of serviceably uniformly applying a viscous material such as cream solder.SOLUTION: A dispenser needle 130 comprises an outer cylinder 114 forming a circular or polygonal cross-sectional shape, an inner cylinder 115 smaller in outer diameter than an inner diameter of the outer cylinder 114 and forming a circular or polygonal cross-sectional shape, and a spacer for connecting the outer cylinder 114 and the inner cylinder 115 by providing a prescribed clearance therebetween, in which a passage 116 for passing a viscous material is formed between the outer cylinder 114 and the inner cylinder 115, and a discharge port 117 composed of an opening of the passage 116 is formed in an end part of the outer cylinder 114 and the inner cylinder 115. The dispenser needle 130 can apply the viscous material on a conductor layer 125 provided in an opening edge part of the through-hole by inserting a pin terminal 126 inserted into the through-hole 124 of, for example, a wiring board 123 into a space 118 of the inner cylinder and discharging the viscous material such as cream solder from the discharge port 117.SELECTED DRAWING: Figure 2
