For example, a glue or an adhesive is applied to the aggregate (50) of a natural bamboo or plastic fan, and the covering material (40) such as paper, resin film, or cloth is sandwiched from both sides, and the fan above the aggregate is sandwiched. It is a fan attached to the grip (55),
In addition, a handmade fan is made by applying glue or adhesive to the inside of the covering material (40), and then aligning the glue surfaces on the aggregate (50) side of the fan and pasting the covering material (40) together. Although typical, it is inefficient and inefficient in the above method, and it is difficult to mass-produce it because of high cost.

ことができなかった。However, products using these plastics are mostly incinerated as a treatment method when they are to be disposed of. However, this method uses harmful gas or high temperature when incinerated. Therefore, a treatment method such as embedding in the soil is preferable from the problem of damaging the incinerator, etc., but the paper base part is decomposed, but the thermoplastic resin layer of the coating material and the plastic aggregate are decomposed. Without it, it will remain semi-permanently. Further, when manufacturing a fan, a natural rubber-based adhesive may be used by avoiding a coating material made of a thermoplastic resin, but when an adhesive is used,
A separator (release paper) is required on this surface. Therefore, the separator has to be peeled off by manual work or the like and then pressure-bonded, which causes an extra step and cannot be efficiently manufactured.
