To provide a coating material-extruding container excluding and drawing back a coating material with high accuracy.
This coating material-extruding container 100 includes: a filling member 1 filled with the coating material M; and a piston 7 inserted into the filling member 1 and airtightly contacting with the filling member 1. The advancing and retreating piston 7 includes: a ventilation part 110 ventilating air A between the coating material M and the piston 7 such that the air A is discharged; and a valve mechanism 111 opening/closing the air ventilation of the ventilation part 110. In the coating material-extruding container 100, because the air ventilation of the ventilation part 110 is opened by the valve mechanism 111 in piston 7 advance to discharge the air A between the coating material M and the piston 7, it can be suppressed that bad influence extends over the piston 7 advance by the air A. Because the air ventilation of the ventilation part 110 is closed by the valve mechanism 111 in piston 7 retreat to suitably maintain an airtight state between the coating material M and the piston 7, sucking effect by decompression can be certainly exerted.
