Abstract: A treatment device and an endoscopic treatment method are disclosed. The treatment device includes a first pipeline that is made of material having electrical insulation, and includes an internal space; an electrode that is energizable with high frequency current; a distal-end tip that is attached to a distal end of the first pipeline, and includes a distal-end opening in communication with the internal space of the first pipeline; and a second pipeline that is inserted through the first pipeline and through which liquid can pass. The endoscopic treatment method includes puncturing a treatment target and performing a local injection using the treatment device.
