JOINT STRUCTURE OF CERAMIC MEMBER AND METAL MEMBERS
PROBLEM TO BE SOLVED: To provide a joint structure of a ceramic member and metal members having high corrosion resistance against gas while securing joint properties of joint sections.SOLUTION: A joint structure (20) of a ceramic member and metal members being a joint structure joining a ceramic member (50) and metal members (32a and 32b) of a device (10) installed at a location where gas passes through is provided with joint sections (21a and 21b) joining the ceramic member (50) and the metal members (32a and 32b). The joint sections (21a and 21b) include: glass sections (22a and 22b) constituted of glass; and metal solder material sections (23a, and 23b) constituted of a metal solder material having corrosion resistance against the gas greater than that of the glass. Areas where the metal solder material sections (23a, and 23b) are brought into contact with the gas are greater than areas where the glass sections (22a and 22b) are brought into contact with the gas.
【課題】接合部の接合性を確保しつつガスに対する高い耐食性を有するセラミック部材および金属部材の接合構造を提供する。【解決手段】セラミック部材および金属部材の接合構造（２０）は、ガスが通過する部位に設置された装置（１０）のセラミック部材（５０）と金属部材（３２ａ，３２ｂ）とを接合する接合構造であって、セラミック部材と金属部材とを接合する接合部（２１ａ，２１ｂ）を備え、接合部は、ガラスによって構成されたガラス部（２２ａ，２２ｂ）と、ガラスよりもガスに対する高い耐食性を有する金属ロウ材によって構成された金属ロウ材部（２３ａ，２３ｂ）とを有し、金属ロウ材部のガスに接触する面積はガラス部のガスに接触する面積よりも大きいことを特徴とする。【選択図】図３
