PROBLEM TO BE SOLVED: To obtain a grain-like molded article having a straight grain pattern near to nature. SOLUTION: A first material 24 and a second material 25 are used as molten resins in an incompletely mixed state and, before the molten resins enter a cavity, they are brought to such a state that the second material 25 flows along the resin supply end of the cavity and allowed to go toward the resin supply end of the cavity to generate a plurality of branched flows 26 arranged in the direction along the resin supply end of the cavity and these branched flows 26 are allowed to meet with each other. By this constitution, the respective branched flows 26 are brought to an almost constant width state while made adjacent to each other before the molten resins enter the cavity and a plurality of the stabilized branched flows 26 are supplied to the cavity. |
