PROBLEM TO BE SOLVED: To provide a polymer actuator type curving device in an endoscope capable of easily and surely connecting lead wires (electrodes) to a polymer actuator and preventing the enlargement of a curving section. SOLUTION: This curving device is provided with: a substantially tubular conductive polymer layer 33 provided in the curving section 20 near the distal end of an insertion section of the endoscope; electrodes 38 and 39 having contact sections 40 abutting on the outer circumferential face of the conductive polymer layer and supplying a power from a power supply from the contacts section to the conductive polymer layer; and an elastic pushing member 43 elastically contacting with the contact sections 40 and the conductive polymer layer from the outer circumferential side and pushing the contact sections toward the outer circumferential side of the conductive polymer layer.
