PROBLEM TO BE SOLVED: To provide an easily connectable curbstone, without using a tool such as a conventional joint filling cover. SOLUTION: This curbstone 1 has a curbstone body 10. A both end surface shape of this curbstone body 10 has a bottom part 12 and a projection-shaped part 13 for forming both ends of this bottom part 12 upward in a projection shape, and ranges over the whole outer periphery of this projection-shaped part 13, and has a peripheral edge chipped part 14 by the thickness (t) in the direction for crossing the longitudinal direction of the curbstone body 10 in a width (w) along the projection-shaped part 13, and a central chipped part 15 by the thickness t<SB>1</SB>(t<SB>1</SB>≤t) in the direction for crossing the longitudinal direction of the curbstone body 10 in a width W continuing with the peripheral edge chipped part 14 including a central part of the bottom part 12. In the projection-shaped part 13, one side projection part 16 is formed on one side, and the other side projection part 17 is formed on the other side, respectively, with the central chipper part 15 as a boundary.
