<P>PROBLEM TO BE SOLVED: To provide a canister used for an evaporated fuel processing device of an internal combustion engine of an automobile capable of considerably enhancing the adsorption/desorption performance of the evaporated fuel. Ž<P>SOLUTION: The canister 1 for processing the evaporated fuel comprises a tank port 5 communicated with an upper gas chamber of a fuel tank of an automobile, a purge port 6 communicated with an intake passage of an internal combustion engine of an automobile, an atmosphere port 7 opened into the atmosphere, and an adsorbent chamber for storing activated carbon 8 for adsorbing gasoline vapor flowing from the tank port 5 to the atmosphere port 7. The adsorbent chamber consists of a main adsorbent chamber 11, a second adsorbent chamber 12 and a third adsorbent chamber 13. The main adsorbent chamber 11, the second adsorbent chamber 12, and the third adsorbent chamber 13 are arranged in this order between the tank port 5 and the atmosphere port 7. A thermal storage material 9A in which a phase change material for executing the absorption and discharge of the latent heat according to the temperature change is enclosed in a capsule is arranged in the main adsorbent chamber 11 and the second adsorbent chamber 12, and the thermal storage material 9A is not arranged in the third adsorbent chamber 13.
