PROBLEM TO BE SOLVED: To provide a piping member with a copper pipe brazed with good brazing property.SOLUTION: A flare half union is a piping member configured so that a copper pipe 46 is inserted from an insertion surface 81 and brazed, and includes: a cylindrical main body portion 80a; and a nut portion 80b adjacent to the main body portion 80a. The nut portion 80b has the insertion surface 81 formed on an opposite side to the main body portion 80a, and a thickness t80b is larger than that of the main body portion 80a. A copper pipe insertion hole 83 for inserting the copper pipe 46 is formed in the nut portion 80b. Annular grooves 85 are formed in the nut portion 80b near an inlet of the copper pipe insertion hole 83. The annular grooves 85 are more recessed in an insertion direction A11 than the insertion surface 81 around the annular grooves 85.
