To provide a sucking disk attached to scalp detachably to lock hair and being favorable for a wig forming material.

A sucking disk sheet 1 is constituted by connecting a plurality of sucking disks 2 vertically and horizontally by a lateral rod 3, and individual sucking disk 2 has a bowl-shaped suction body 4, three columnar bodies 6 erected on a circular flat face 5, an annular body 7 fixed to its top part, and a cylindrical projecting part 8 inside the columnar body. The projecting part 8 has a hollow structure and communicates an inner face of the projecting part with an inner face of the bowl-shaped suction body by a hole 9 provided at the center of the circular flat face 5. Since adequate number of hairs are locked in the annular body 7, this sucking disk can be used as a constituent member of a detachable wig at arbitrary time. Since the projecting part 8 forms a space having negative pressure as a two step configuration, suction force is increased. By cutting a lateral rod 3 connected with the other adjacent bowl-shaped suction body 4 appropriately, the sucking disk sheet 1 can be used as a face-like or row-like or individual sucking disk.
