  • Multilayer ceramic substrate, method for manufacturing the same, and piezoelectric resonator component
    Patent number: 7352116
    Abstract: A multilayer ceramic substrate includes a multilayer composite including a first material layer including glass, a second material layer including a ceramic, disposed in contact with the first material layer, and an internal electrode including an electroconductive material, disposed in contact with at least one of the first material layer and the second material layer. The first material layer is sintered, and is firmly bonded to the second material layer by diffusing or permeating a portion of the glass in the first material layer into the second material layer. The internal electrode includes a main portion and a lead-out portion extending from the main portion to a side surface of the multilayer composite, and the internal electrode includes a ceramic powder at least in the lead-out portion.
