STICKING BODY HOLDING MEMBER
Provided is a sticking body holding member capable of suppressing generation of slack in a carrier tape without excessively strong winding of the carrier tape. A sticking body holding member includes a plurality of sticking bodies, a carrier tape, and a reel. The sticking bodies are each configured to have a planar shape, and each include a first surface being an adhesive surface that is stickable with respect to an adherend. In the carrier tape, the plurality of sticking bodies are stuck and arranged in a line. The carrier tape is wound around the reel. A second surface of the sticking body is provided with an adhesive region having adhesiveness and an adhesion suppressing region where adhesiveness is suppressed, and the second surface of the sticking body is configured to have weaker adhesiveness than adhesiveness of the first surface.
