An endoscope device includes a flexible insertion portion in which a channel is formed a flexible tube portion that is disposed at a proximal end portion of the insertion portion a first bending portion that is disposed more distal than the insertion portion within the insertion portion a second bending portion that is disposed more distal than the first bending portion of the insertion portion an observation portion that is disposed more distal than the second bending portion of the insertion portion and configured to acquire an image on the front of the insertion portion a first drive portion that is configured to bend the first bending portion with respect to the distal end portion of the flexible tube portion by advancing or retracting a first operation wire which is connected to the first bending portion a second drive portion that is configured to bend the second bending portion with respect to the distal end portion of the first bending portion and a control portion that is configured to control generating a second drive signal driving the second drive portion based on a first drive signal driving the first drive portion, and control sending the second drive signal to the second drive portion while sending the first drive signal to the first drive portion, wherein the first drive portion releases the holding of the first operation wire based on the first drive signal sent from the control portion, and the second drive portion bends the second bending portion based on the second drive signal sent from the control portion to cause the observation portion to face a treatment target.
