    Abstract: In the multi-layer inductor, the internal electrode includes the auxiliary conductor, and the auxiliary conductor is jointed to the external electrode at the end face. Therefore, when a defect occurs in a part of the through conductors, a current flows through the remaining through conductor(s) and a current also flows through the auxiliary conductor. Therefore, overheating at the joint surface between the remaining through conductor(s) and the external electrode can be prevented, and cutting and/or fusion starting from the joint surface can be prevented.
