Abstract
Abstract A fuel cap which is to be attached to a filler neck which is open for a fuel supply has a closure which is to be fitted to the filler neck and which is made of a resin, and a shell which covers an upper part of the closure and which is made of a resin. The shell is formed by an electrically conductive resin material which has a surface resistance of 10 11 Ω or less, or has a volume resistance of 10 11 Ω·cm or less, and a discharge rib portion is integrally formed on the inner peripheral face of the shell. In a state where the fuel cap is attached to the filler neck, the distance between the discharge rib portion and the filler neck or the body of an automobile is 3 mm or less.
