The present invention provides amorphous silica particles having high oil absorbency and high structural characteristics, wherein the oil absorbency is hardly decreased even when a high load is applied to the amorphous silica particles. In particular, amorphous silica particles are provided, wherein the maximum value of ΔVp/ΔRp (where Vp is the pore volume [mm3/g] and Rp is the pore radius [nm]) is 20 mm3/nm•g-1 or more in the pore distribution curve obtained by a benzene adsorption isotherm, and the pore peak radius when the ΔVp/ΔRp value is maximum is from 20 nm or more to 100 nm or less. |
