<p>PURPOSE:To provide a laminated varistor which can reduce leak currents while lowering voltage. CONSTITUTION:A laminated varistor 1, which gets voltage nonlinear property at the interfaces between semiconductor ceramic layers 2 and inner electrodes 3 by piling the semiconductor ceramic layers 2 and inner electrodes 3 alternately to make a sintered body, is constituted. And glass layers 7 are interposed between the above ceramic layers 2 and the inner electrodes 3. Moreover, these glass layers 7 contain B, Si, and at least two kinds out of Pb, Bi, and Zn, and the thickness of the above glass layer is 0.3mum or below.</p> |
