Abstract
The work processing apparatus of the present invention comprises: a processing section for processing or treating a work; and a liquid chemical supplying section for supplying a liquid chemical to the processing section. The liquid chemical supplying section includes: a plurality of liquid chemical bags for storing the liquid chemical; a bag holding part in which the liquid chemical bags are attached and held; and a liquid feeding part, to which the liquid chemical bags are detachably connected, for feeding the liquid chemical from the liquid chemical bags to the processing section. Each of the liquid chemical bags is produced by overlapping flexible resin sheets with each other and welding their edge parts to form into a bag. Each of the liquid chemical bags has a port part communicating with an outside. A joint with a valve is attached to each of the port parts.
