摘要： To provide a fluid contact member whose corrosion resistance is particularly further improved than that in the related art. In order to solve this problem, a fluid contact member 10 includes a fluid contact portion 1 configured to be in contact with a fluid, the fluid contact portion 1 has a cobalt-based alloy phase 2 having a dendrite, and a compound phase 3 formed in an arm space of the dendrite and containing chromium carbide, and among a plurality of secondary arms 5 extending from one primary arm 4 constituting the dendrite, an average interval between adjacent secondary arms 5 is 5 μm or less. At this time, the average interval is preferably 3 μm or less. Further, the compound phase 3 is preferably formed discontinuously in the dendrite arm space.
