A predetermined deodorizing effect and a moisturizing effect can be easily ensured, activated carbon can be prevented from falling off, and the structure is simple, easy to manufacture at low cost. SOLUTION: A mask filter 4 is obtained by impregnating a moisturizing liquid 19 into an activated carbon sheet 12 in which activated carbon 16 is supported on an air permeable sheet base material 15 via an adhesive, and an air permeable sheet base material 18. And an impregnated sheet 13. The activated carbon sheet 12 has shape retention, and the activated carbon sheet 12 is folded in half, and an impregnated sheet 13 is sandwiched between them. The activated carbon 16 is made of bamboo charcoal particles, and the sheet base material 15 of the impregnated sheet 13 is made of cellulose-based nonwoven fabric. [Selection] Figure 4 |
