ABSTRACT:
To provide an activated carbon sheet molding that can reduce a leak amount of fuel vapor, realize small ventilation resistance, and is excellent in moldability and strength, and an element for a fuel evaporative emission preventing device for preventing evaporative emission of fuel vapor from a fuel tank system and an intake system by using the activated carbon sheet molding. The object can be achieved by an activated carbon sheet molding made of activated carbon that satisfies b/a=0.3 through 0.55 provided that a 100%-concentration n-butane adsorbing amount per 100 parts by weight of activated carbon at 40° C. is defined as a parts by weight, and a 1%-concentration n-butane adsorbing amount is defined as b parts by weight.
