A vehicular resin molded article is formed by solidifying a molten resin filled in a cavity of an injection mold and having a concave gate mark formed by a valve pin and remaining thereon in which L/T is 190 or more where L is a flow distance of the molten resin from the gate mark to a filling terminal and T is a maximum thickness. When the valve pin is moved to the cavity side and is pressed against the molten resin, since the contact area of a tip end portion with respect to the molten resin in the vehicular resin molded article increases and the temperature of the tip end portion in the valve pin tends to decrease, the portion of the vehicular resin molded article where the valve pin is pressed against is sufficiently solidified and string drawing or silver streak is less likely to occur.
