Abstract
A curved portion at an inner circumferential face on a bend direction inside of a bend has a circular arc shape. By configuring the curved portion with a circular arc shape, a recess, serving as an example of a cross-sectional area enlargement portion that enlarges the cross-sectional area of a flow path of a pipe body running along a direction of an axial line, is formed in the inner circumferential face on the bend direction inside of the bend.
