A structural body is composed of a fibrous structural body, and particles at least part of which are present in the form of an aggregate attached to the fibrous structural body. The structural body can absorb and then vaporize liquid quickly and stably. The structural body can be used as a wick of vapor-dispensing device, such as a liquid-absorption-type heat vapor-dispensing insecticidal device.[IN-CHE-2009-02190A]
