Exhaust component

An exhaust component comprising:

• a first member forming a first flow path for exhaust gas;
• and
• a second member forming a second flow path, the second flow path having a smaller cross-sectional area than the first flow path,
• the first member including a hole-forming portion forming a through hole,
• the hole-forming portion including an edge portion, the edge portion protruding toward an outside of the first member in a manner curved from a periphery of the through hole, the edge portion surrounding the through hole,
• the second member including an upstream end portion located on an upstream side of the second flow path, the upstream end portion being joined to the hole-forming portion by welding so as to cover an outer-peripheral surface of the hole-forming portion,
• the upstream end portion including an end face formed such that an angle formed with the outer-peripheral surface of the hole-forming portion is an obtuse angle, the end face being exposed on the outside of the first member and the second member, and
• the second flow path being a flow path for the exhaust gas that has passed through the through hole and flowed in from the upstream end portion.
