MANUFACTURING METHOD FOR CERAMIC MEMBER AND CERAMIC MEMBER
To provide a ceramic member that suppresses the exfoliation of an external electrode from the ceramic member while maintaining high compactness of the ceramic member.SOLUTION: A manufacturing method for ceramic member includes: a preparation process of preparing a laminate that comprises a first ceramic green sheet body with external electrodes formed on a first surface and a second ceramic green sheet body, and where the second ceramic green sheet body is laminated on a second surface side of the first ceramic green sheet body; a firing process that makes a ceramic firing body with a first ceramic part and a second ceramic part by firing the laminate; and a HIP process that makes the ceramic member by conducting HIP to the ceramic firing body. After the firing process and before the HIP process, density of the second ceramic part is higher than that of the first ceramic part.SELECTED DRAWING: Figure 4
【課題】セラミックス部材の高い緻密性を維持しつつ、外部電極のセラミックス部材からの剥離が抑制されたセラミックス部材を得る。【解決手段】セラミックス部材の製造方法は、第１の表面に外部電極が形成された第１のセラミックスグリーンシート体と、第２のセラミックスグリーンシート体とを含み、第１のセラミックスグリーンシート体の第２の表面側に第２のセラミックスグリーンシート体が積層された積層体を準備する準備工程と、積層体を焼成することによって、第１のセラミックス部と第２のセラミックス部とを備えるセラミックス焼成体を作製する焼成工程と、セラミックス焼成体に対してＨＩＰを行うことによって、セラミックス部材を作製するＨＩＰ工程と、を備える。焼成工程後、ＨＩＰ工程前において、第２のセラミックス部の密度は第１のセラミックス部の密度より高い。【選択図】図４
