Abstract

The present invention relates to method and apparatus for forming a thick film circuit by discharging a thick film paste from a paste discharging hole of a drawing nozzle and drawing a desired pattern on a substrate. The paste discharging hole has a substantially wide configuration and the drawing nozzle is rotated about its axis of rotation so that the longitudinal direction of the elongated cross-section of the paste discharging hole is substantially normal to the direction in which the drawing nozzle is moved with respect to the substrate.
