A fuel vapor processing device may include a casing having an adsorption chamber defined therein, an adsorption material disposed within the adsorption chamber, a heating device capable of heating the adsorption material, and a passage member communicating between the adsorption chamber and the atmosphere. The passage member defines a flow space facing to an outer circumferential surface of the casing, so that heat can be transmitted between the adsorption chamber and the flow space.
