An endoscope device includes a handle portion, a clamping portion and an insertion portion. The handle portion includes a main circuit board. The clamping portion is connected to the handle portion. The insertion portion is connected to the clamping portion and includes a lens, an image sensor corresponding to the lens and a flexible circuit board electrically connected to the image sensor. The lens and the image sensor are located at a distal end of the insertion portion away from the clamping portion. The flexible circuit board extends from the distal end to the handle portion through the clamping portion and electrically connected to the main circuit board.一種內視鏡裝置，包括把手部、夾持部及插管部。把手部包括主電路板。夾持部連接於把手部。插管部連接於夾持部，且包括鏡頭、對應於鏡頭的影像感測器及電性連接於影像感測器的可撓電路板，其中鏡頭及影像感測器位於插管部在遠離夾持部的前端部分，且可撓電路板從前端部分經過夾持部延伸至把手部，而電性連接至主電路板。
