Abstract:
1. A thin-film device comprising: an underlying layer having a bottom surface and a top surface that face toward opposite directions, and a side surface that couple the bottom surface and the top surface to each other; a conductor layer disposed on the top surface of the underlying layer; and a terminal electrode connected to the conductor layer; and a coating layer having a bottom surface and a top surface that face toward opposite directions, and a side surface that couples the bottom surface and the top surface to each other, wherein: the conductor layer has a protruding portion that protrudes to extend more outward in a lateral direction than the side surface of the underlying layer and the side surface of the coating layer; at least a portion of the conductor layer other than the protruding portion is disposed between the top surface of the underlying layer and the bottom surface of the coating layer; and the terminal electrode has a concave portion that accommodates and touches at least part of the protruding portion, and the terminal electrode touches the side surface of the underlying layer and the side surface of the coating layer.
