SOLUTION: This canister unit has a casing 2 having an outer wall surface 2A and an inner wall surface 2B, and forming the inside of the inner wall surface 2B as a cavity. A part between the outer wall surface 2A and the inner wall surface 2B is formed as an adsorbent storage part 4 for storing an adsorbent. The cavity formed inside the inner wall surface 2B is formed as a pump installing part 5 for arranging a fuel pump 7 for drawing up fuel, and the canister and the fuel pump 7 are integrated into a unit. The casing 2 is provided with an installation part 10 for installing the unit in a fuel tank 30 by arranging the unit inside the fuel tank 30 for storing the fuel drawn up by the fuel pump 7. A communicating part 2D for communicating the pump installing part 5 with the fuel tank is also formed in a lower part of the casing 2, and a suction port 7a of the fuel pump 7 is arranged in the lower part of the casing 2.
