A cantilever-type standoff includes a column body, a plurality of cantilevers, a plurality of blocking plates, and a plurality of bumps. The cantilevers are respectively disposed on opposite end surfaces of the column body. The blocking plates are respectively parallel to the cantilevers. A plurality of clamping grooves are respectively defined by the blocking plates and the cantilevers. The bumps are respectively disposed on surfaces of the cantilevers facing the blocking plates.
