Abstract
The invention provides a functional particle carried sheet constituted by a particle layer having a two-layer structure with a reduced pressure loss, in which a function of a functional particle is increased. The sheet is formed as a sharp shape in a peak portion and a trough portion of a pleat at a time of pleating process, the functional particle does not jump out of a base material, and the sheet has a good precision of a fold peak height, is easily manufactured, and can achieve a low cost. The invention provided a functional particle carried sheet having a first particle firmly attaching sheet structured such that a functional particle is firmly attached onto a surface of a first breathable base material via a first adhesive agent, and a second particle firmly attaching sheet structured such that a functional particle is firmly attached to a portion except band-like space portions provided at a fixed interval on a surface of a second breathable base material, via a second adhesive agent, in which the functional particle in the first particle firmly attaching sheet and the functional particle in the second particle firmly attaching sheet are bonded via a third adhesive agent.
