A canister includes a casing having a gas passage which extends from a first passage end formed with a charge port to let in fuel vapor and a purge port to let out the fuel vapor, to a second passage end formed with an atmospheric air port to let in air, and which includes a heat storing and adsorbing chamber in which a granular adsorbing material and a granular heat storing material are held. The granular heat storing material contains capsules each including a phase-change material enclosed in a multilayer outer shell which includes an inner layer of a hydrophobic resin and an outer layer of a hydrophilic resin covering the inner layer.
