Abstract: The present fluid container includes a first metallic member, a second metallic member, an adherence par, a first interface, and a second interface. Each of the first and second metallic members contains chromium. The adherence part is made of an oxide containing chromium as a primary component. The adherence part adheres the first metallic member and the second metallic member to each other. The first interface is provided as an interface between the first metallic member and the adherence part. The second interface is provided as an interface between the second metallic member and the adherence part. The first interface includes a first wavy portion. The first wavy portion repeatedly winds in a thickness direction. The first wavy portion extends along an outer peripheral edge of the first metallic member.

Abstract: There is provided a copper alloy bonded body composed of members made of an age-hardenable copper alloy, the members diffusion-bonded to one another, wherein a bonding interface between the members remains. In the bonded body, the content of beryllium in the age-hardenable copper alloy is 0.7% by weight or less, and, in a laser microscope image of a section including the bonding interface, a ratio of a total length of a line segment corresponding to a discontinuous region relative to an entire length of a bonding interface line defined along the bonding interface and a position where the bonding interface was present is 3.5% or more. The discontinuous region is defined as a region where, when a plurality of perpendicular lines is drawn with respect to the bonding interface line at a pitch of 5 μm, three or more adjacent perpendicular lines do not intersect with the remaining bonding interface.

Abstract: A sensor element includes an element body, a reference electrode, a measurement-object gas side electrode, a first conducting section that has a reference electrode terminal and a reference electrode lead, and a lead insulation layer. The reference electrode lead is configured to flow a reference gas, which serves as a reference for detecting the specific gas concentration in the measurement-object gas, to the reference electrode. A region of 50% or more, from an end on the reference electrode side, of the total area of the lead insulation layer in a planar view is configured as a dense region with a porosity of 5% or less.
