First and second major-surface terminal electrodes are arranged on a major surface of the capacitor body. First and second internal electrodes which are opposed to each other within the capacitor body are respectively electrically connected at ends thereof to the first and second side-surface terminal electrodes, and are also respectively electrically connected to the first and second major-surface terminal electrodes through via hole conductors. With this arrangement, the directions of the currents flowing within the multi-layer capacitor are diversified, and the lengths of current-carrying paths are shortened so as to achieve a very low ESL value.

摘要： A multi-layer capacitor is constructed to minimize equivalent series inductance, increase resonance frequency, reduce the size of the capacitor and greatly improve the ease of mounting of the capacitor. A dimension in a length direction and a dimension in a width direction of a capacitor body are substantially equal, and a pattern of opposing first and second internal electrodes is substantially square. First lead-out portions of the first internal electrode and second lead-out portions of the second internal electrode are extended onto two side surfaces and two end surfaces. First external electrode terminals connected to the first lead-out portions and second external electrode terminals connected to the second lead-out portions are arranged so that they alternate adjacently and are arranged such that oppositely disposed external electrode terminals have opposite polarities.
