摘要： A condenser and a wiring board are provided to prevent a crack when embedding the board by increasing the toughness of a surface layer. A condenser includes a main body(104) and a plurality of condenser-via-conductors(131,132). The main body of a plate shape has a condenser main plane(102) and a condenser rear plane(103). The condenser-via-conductors are arranged on the main body, and are arranged to be expanded along a thickness direction of the main body. The main body has a first dielectric stacking unit(107), and a dummy electrode(154) which are alternatively stacked. The first dielectric stacking unit has a plurality of first dielectric layers(105) and a plurality of internal electrodes which are alternatively stacked. The internal electrodes are contacted with an outer circumference unit of the condenser-via-conductors. The dummy electrode is not contacted with an outer circumference of the condenser-via-conductors and second dielectric layers. The second dielectric stacking unit is exposed to the surface unit of the main body.
