Provided is a chemical agent vaporizing/discharging device which can efficiently vaporize and discharge a chemical agent from a chemical agent retainer, and sufficiently diffuse the chemical agent, even when the device is used in a relatively large space or outdoors. A chemical agent vaporizing/discharging devicecomprises: a chemical agent retainerhaving a chemical agent retention layerincluding intersticesfor allowing retention of a volatile chemical agent, and a gas permeable layerincluding voidshaving a size larger than a size of the interstices; and a rotational drive partfor driving the chemical agent retainer. A shape and a size of the chemical agent retainer, and a rotational speed of the rotational drive part, are set so that a centrifugal effect of 10 to 150 (G) is obtained during rotation of the chemical agent retainer

Device and method for vaporizing/discharging chemical agent

A three-dimensional structure is provided which is obtained by molding a volatile chemical-containing resin composition into a plate form, wherein the three-dimensional structure includes through-holes penetrating therethrough from the front to the back thereof, the through-holes have peripheries having a shape selected from polygonal, circular, circular arc and spiral shapes when the three-dimensional structure is viewed from the front, and the peripheries of the through-holes are formed on a single plane or on a smoothly curved imaginary surface.
