Abstract
Provided are an adsorption sheet and an air-purifying filter, which can have low air-flow resistance and high deodorizing performance and be resistant to clogging by dust, from which a powdered adsorbent can hardly drop off, and in which any attached agent can hardly lose its effect. Such a product can be obtained by a process including the steps of: sufficiently premixing an agent-bearing activated carbon powder and a powdered thermoplastic resin to form a mixed powder; then spreading the mixed powder on a base sheet having a certain bulkiness and bearing an agent; stacking an air-permeable sheet thereon; and hot-pressing them.
