摘要： An electronic device includes electrode layers and supports. The electrode layers and supports include an electrode layer and a support on each of both sides of an electronic functional layer in a thickness direction. Taking-out electrode parts from the electrode layers are exposed in a plane region of at least one of the supports on the both sides.
