Abstract
An object is to provide a new form of adsorbent suitable for a high performance canister. An adsorbent including activated carbon is used as the adsorbent for the canister and satisfies the following conditions. P0.2/100 expressed by Equation 1: P0.2/100=X÷Y×100 (Equation 1) is 18% or more, in Equation 1, X represents an amount of adsorbed n-butane gas per 100 parts by weight of the adsorbent at 25° C. under an atmosphere where a gas pressure of n-butane gas is 0.2 kPa, and Y represents an amount of adsorbed n-butane gas per 100 parts by weight of the adsorbent at 25° C. under an atmosphere where a gas pressure of n-butane gas is 100 kPa.
