Provided is a fuel filler cap canister including activated carbon used to adsorb fuel in a fuel tank for preventing the fuel from being discharged, with improved adsorption efficiency for the activated carbon. The fuel filler cap canister for use with a fuel filler cap to be removably attached to a fuel filler port of a fuel tank includes: a base part provided with an attachment section to be attached to the fuel filler cap and a communicating hole that is in communication with the fuel tank, the communicating hole being formed in the base part in either one of substantially a central portion or a vicinity of an outer edge portion; and a case member to be assembled to the base part and provided with a volumetric space inside of the case member, wherein the volumetric space is provided with a spiral rib formed therein, the spiral rib extending from either one of an opposing face of the case member facing the base part or an opposing face of the base part facing the case member toward either one of the base part or the case member, the spiral rib forms an adsorption path having a first end that is in communication with the communicating hole and a second end that is in communication with an atmosphere communicating hole formed in either one of a vicinity of a peripheral edge or substantially a central portion of the opposing face of the case member facing the base part, and the adsorption path is filled with an adsorbing device.
