This invention provides a tape set capable of increasing the portion (share) for tape pieces in a base paper in the shaping of tape pieces. A tape set 1 includes at least one tape T1 and at least one tape T2, each extending in the longitudinal direction. The tape T1 and tape T2 each include a wavy part W having one or more basic components K, both side edges of which having an outward-facing convex shape from a first bottom point P to a second bottom point P via a vertex Q. The tape T1 and tape T2 are arranged in a width direction orthogonal to the longitudinal direction so that the wavy parts W of the tape T1 and tape T2 are adjoined to each other. The tape T1 further includes a section T1-1 that continues from an edge of the wavy part W on one end side.
