A highly viscous fluid discharging apparatus includes: a nozzle including a discharge opening having a predetermined inner volume, and a widened portion formed at a position immediately before the discharge opening and expanding from the discharge opening; a plunger capable of opening and closing the discharge opening by causing the leading-end portion of the plunger to move away from and to move towards the widened portion; and a driver configured to move the plunger in a direction of closing the discharge opening against a biasing force that biases the plunger in a direction of opening the discharge opening. During a stand-by period, the discharge opening is kept closed by an action of the plunger that is caused by the driver to press the leading-end portion onto the widened portion. |
