Abstract
In recent years, ceramic laminated devices are becoming a focus of great attention as considerable contribution to the miniaturization of high frequency wireless equipment such as a cellular phone, but it is difficult for the conventional ceramic laminated device to secure reliability while maintaining favorable high frequency characteristics. The present invention provides a ceramic laminated device including a reinforcement electrode, which is formed inside a laminated body in which a plurality of ceramic layers, a plurality of inner electrodes and inter-layer via holes are stacked, not electrically connected with inner electrodes nor inter-layer via holes but mechanically connected with the ceramic layers.
