PROBLEM TO BE SOLVED: To provide a tubular body in which a fluid or powder easily flows along the axial direction of a conduit line and can be promptly transported, and in which the collision of the fluid or the powder can be suppressed in the conduit line so that contamination into the fluid or the powder is relatively little and durability thereof is relatively high.SOLUTION: A tubular body 10 has a conduit line 1 and is made of a ceramic sintered material, and a center axis of said conduit line has a curved portion 5. An inner circumference 20 of said conduit line has a plurality of irregular strip parts 2 individually continuous along a direction parallel to said center axis.SELECTED DRAWING: Figure 1 |
