PROBLEM TO BE SOLVED: To provide a compact resin joint boot excellent in durability. SOLUTION: The resin joint boot is composed of a small diameter cylindrical part 12, a large diameter cylindrical part 14 and a bellows part 16 integrally connecting the small diameter cylindrical part 12 and the large cylindrical part 14. Each crest of a crest group 28 in the bellows part 16 near the small diameter cylindrical part is formed to have a height H1 to be lower than the height H2 of each crest of a crest group 30 near the large diameter cylindrical part. In the crest group 28 near the small diameter part 28, the each crest 24a, 24b, 24c are laid toward the side of the small diameter cylindrical part 12, and inclined surfaces 24a1, 24b1, 24c1 of a large diameter cylindrical part side of the each crest are formed substantially in parallel in a cross sectional shape along an axial direction.
