| 摘要 |
<p>A current limiter composed of a PTC element the resistance of which is abruptly increased by rise of temperature above a resistance transition temperature and a pair of electrode plates secured to opposite surfaces of the PTC element, wherein the PTC element is formed thinner at its outer peripheral portion than at its central portion so that the specific resistance of the central portion becomes smaller than that of the outer peripheral portion.</p> |
