If the mass ratio of the active ingredient to the ceramics is smaller than 1/10, the ceramics are contained more than necessary with respect to the active ingredient, resulting in economic waste. Alternatively, the active ingredient may be too small to produce the effect. On the other hand, if the mass ratio of the active ingredient to the ceramics is larger than 10/1, the ceramics cannot hold the active ingredient, and the stability of the active ingredient may decrease.
  • Ceramics are silicic acid-based colloidal silica, calcium silicate, ethyl silicate, sodium silicate, potassium silicate, lithium silicate, alumina-based calcium aluminate, ⁇ -alumina, boehmite, alumina sol, and phosphoric acid-based.

At this time, it is also possible to simultaneously contain an antibacterial agent, a flame retardant, a pigment for coloring and the like at the same time as the ceramics.

  • Examples thereof include a method of sandwiching and crimping between sheets of non-woven fabric.
  • the mass ratio of the bander to the ceramics carrying the active ingredient is preferably smaller than 1/1. This is because when the amount of the binder is large, the exposed portion of the ceramics in the filter medium is reduced, and the amount of the active ingredient released is reduced, so that the obtained effect is lowered. Further, the mass ratio of the bander to the ceramics carrying the active ingredient is preferably more than 1/10 in the amount of the binder. This is because if the amount of the binder is smaller than this, it is practically difficult to fix the ceramics to the filter medium.
