发明名称 MULTILAYER ELECTRONIC COMPONENT
摘要 A multilayer electronic component includes an element body having an internal electrode layer and a dielectric layer. These are substantially parallel to a plane including a first axis and a second axis and are alternately laminated along a third axis direction. Side surfaces oppositely facing in the first axis direction are respectively equipped with an insulating layer. End surfaces facing each other in the second axis direction are respectively equipped with an external electrode. An end portion in the first axis direction of the internal electrode layer is recessed from an end portion in the first axis direction of the dielectric layer to the inner side along the first axis direction. A main component of the internal electrode layer is Ni. A reaction portion is between the end portion in the first axis direction of the internal electrode layer and the insulating layer.
