Abstract:
1. A chip resistor, comprising: a substrate made of an insulating material, the substrate including a first surface, a second surface opposite the first surface and a thickness defined between the first surface and the second surface; a pair of electrode elements formed on the first surface of the substrate and spaced apart from each other on the first surface; a resistive layer formed on the first surface of the substrate and electrically connected to the pair of electrode elements; and a protective layer provided to cover the resistive layer; wherein: the first surface of the substrate is a mount side surface to face toward a mounting target; the pair of electrode elements comprise each an electrode layer and a conductive layer, the electrode layer being electrically connected directly to the resistive layer, the conductive layer being formed on the electrode layer; the electrode layer of each electrode element includes a first electrode layer and a second electrode layer, the first electrode layer being provided directly on the first surface of the substrate, the second electrode layer being provided directly on the first electrode layer; a boundary is defined between the second electrode layer and the conductive layer in each of the electrode elements, and the boundary as a whole is positioned closer to the substrate than an end surface of the protective layer in a thickness direction of the substrate; the substrate includes a pair of side surfaces opposite to each other and spaced apart from each other in a direction in which the electrode elements are spaced, and each of the side surfaces is exposed at least partially from a respective one of the conductive layers; and in each electrode element, the first electrode layer and the second electrode layer include ends, respectively, that are flush with a corresponding one of the pair of the side surfaces.
