MULTILAYER BOARD AND MANUFACTURING METHOD

摘要

PURPOSE: To provide a multilayer board on which the electrodes has strong adhesion strength to glass-containing insulation layers and excellent solderability, and manufacturing method of the board. CONSTITUTION: Manufacturing processes of the multilayer board comprises a process for applying an electrode paste on the surface of a green sheet containing a crystallized glass with the viscosity before crystallization of <= 10 6.0 Pa.s in order to form electrodes, a process for forming a laminated compression body by laminating and compressing the green sheet on which the electrode paste is applied, and a process for sintering the laminated compression body. The green sheet includes the crystallized glass with the viscosity before crystallization of <= 10 6.0 Pa.s and a ceramics, and the volume ratio of the crystallized glass is in the range of 45 to 80%.
