Disclosed are a multi-layered voice coil plate and a flat-type speaker using the same, the multi-layered voice coil plate being configured to dramatically alleviate difficulty in designing and manufacturing a multi-layered voice coil pattern. The multi-layered voice coil plate, according to one aspect of the present invention, comprises: first-type voice coil pattern layers formed in the shape of a track and connected from a first outer via hole outside the track to an inner via hole inside the track; and second-type voice coil pattern layers formed in the shape of a track and connected from a second outer via hole outside the track to the inner via hole inside the track. The first-type voice coil pattern layers and the second-type voice coil pattern layers are laminated to be insulated from each other, and the first outer via hole, the second outer via hole and the inner via hole are electrically connected through a interlayer conductor. |
