Abstract: Provided is a canister that can inhibit discharge of evaporated fuel to the atmosphere. One aspect of the present disclosure is a canister. The canister includes a charge port, a purge port, an atmosphere port, a main chamber to which a charge port and a purge port are connected, a sub chamber to which the atmosphere port is connected, an intermediate chamber arranged between the main chamber and the sub chamber in a flow path of an evaporated fuel, the intermediate chamber being connected to each of the main chamber and the sub chamber, a first adsorbent stored in the main chamber, second adsorbent stored in the sub chamber, and a third adsorbent stored it intermediate chamber. An adsorption capacity of the third adsorbent is smaller than each of an adsorption capacity of the first adsorbent and an adsorption capacity of the second adsorbent.
