摘要： A laminated-type piezoelectric element 1 is provided, which comprises a first external electrode layer 33, which is located at a side area of the laminated-type piezoelectric element 1, is electrically continuous to internal electrode layers 21, and comprises plural expansible and contractible opening portions 33a in a stacking direction of the laminated-type piezoelectric element 1. As the first external electrode layer 33 is connected to the laminated-type piezoelectric element 1 with an electrically conductive adhesive member 32 and the electrically conductive adhesive member 32 is narrower than the first external electrode layer 33, the electrically conductive adhesive member 32 penetrates into the opening portions 33a of the first external electrode layer 33 to form connections in a shape of an anchor. Therefore, the first external electrode layer 33 is firmly connected to the laminated-type piezoelectric element 1.

摘要： A multilayer piezoelectric element has a pair of outer electrodes and a multilayer ceramic body composed of piezoelectric layers and inner electrode layers which are alternately stacked. The outer electrodes are formed on a pair of electrode connecting surfaces in the outer circumference surfaces of the multilayer ceramic body. Each outer electrode electrically connected to the inner electrode layers through connecting material is composed of a fixed part, a free part having plural expandable-openings, and a rigid part. The fixed part is electrically contacted with the connection material. A sectional area of the rigid part is rather than that of each of the fixed part and the free part in a width direction of the outer electrode. Each outer electrode has at least one part where the fixed part, the free part and the rigid part are arranged in order in the width direction.

摘要： A circuit board, onto which an electronic component is to be mounted, is provided with insulating core substrates and patterned metal plates. The metal plates are bonded to at least one side of the insulating core substrates. The insulating core substrates and the metal plates form a laminated body, in which a gas-vent hole is provided. The gas-vent hole is formed so that when the electronic component is mounted, the gas present between the insulating core substrates and the metal plates expands and is released to a side open to the atmosphere via the gas-vent hole.
