To provide a liquid jetting apparatus capable of efficiently discharging a waste liquid absorbed and held in an absorbing material by bringing the absorbing material into close contact with an absorbing opening in a cap.

The liquid jetting apparatus is equipped with a recording head 19 jetting the liquid from a nozzle 20 on a nozzle forming face 19a, a cap 23 receiving the waste liquid when the liquid is discharged from the nozzle 20 under a condition that the nozzle forming face 19a of the recording head 19 is sealed, an absorbing mat 37 being compression-deformable which absorbs and holds the waste liquid under a condition that it is stored in the cap 23, a discharging mechanism for discharging the waste liquid absorbed and held in the absorbing mat 37 to the outside of the cap 23 by sucking the waste liquid through a discharging port 36 formed in the cap 23, and an absorbing material adjusting mechanism which adjusts the condition of the absorbing mat 37 in the cap 23 so that the absorbing mat 37 is brought into a close contact with an opening part 36a of the discharging port 36 when at least the discharging mechanism discharges the waste liquid in the cap 23.
