<p>A laminate type semiconductor ceramic capacitor with a varistor function is achieved which allows for an improvement in product yield while ensuring such insulation performance that can withstand practical use, and is suitable for mass production with a favorable ESD withstanding voltage. The semiconductor ceramic forming the semiconductor ceramic layers has a compounding molar ratio m between the Sr site and the Ti site of 0.990@m<1.000, has a donor element such as La present as a solid solution in crystal grains, has an acceptor element such as Mn present in a grain boundary layer in the range of 0.5 mol or less (preferably 0.3 mol to 0.5 mol) with respect to 100 mol of the Ti element, and has the crystal grains with an average grain size of 1.5 mum or less.</p> |
