It is also possible to form a connecting convex piece that is cut and raised in the circumferential direction only on the flange plate 22 and to bond the connecting convex piece to the plate surface of the other flange plate 23.

When the reel 20 is wound around a series of electronic components, the tape member and the flange plates 22 and 2 are formed.
Although there is a risk that paper dust will be generated due to friction with 3 and the like, and the reliability of electronic devices manufactured by this paper dust may be reduced, the flange plate 2 is required to suppress the generation of paper dust.
A resin may be coated on the surfaces of Nos. 2 and 23 and the recessed surface of the cut and raised portion. Alternatively, a high-quality paper material that does not easily generate paper dust even if rubbed may be used.

Further, although the reel 20 uses the flat plate-shaped flange plates 22 and 23, there is a possibility that the flange plates 2 and 23 warp in the direction in which they approach each other.
By using the corrugated products 2 and 23 that extend in the circumferential direction or the radial direction, this warping can be significantly suppressed and the tape member can be reliably wound. Further, instead of corrugation, slits extending in the circumferential direction, the radial direction, or spirally extending may be formed in the flange plates 22 and 23.
