ABSTRACT:
A viscous fluid discharging apparatus is provided for removing air bubbles introduced during the passing of the viscous fluid before being supplied to the substrate. A viscous fluid discharging apparatus according to the present invention includes a viscous fluid storing container, a viscous fluid supplying pump, a viscous fluid filter, and a viscous fluid discharging mechanism provided with a final air bubble filtering means. The fluid material discharging mechanism includes a connecting portion formed on an end of a temperature adjusting mechanism connected to an outlet of the fluid material supplying pump, and a discharging gun. The discharging gun has a sealed joining portion for being sealed and joined to the connecting portion, an air bubble capturing portion for capturing air bubbles from within the viscous fluid, and a viscous fluid path for moving the viscous fluid to an outlet in a sealed state.
