1. A method for manufacturing an Al—

  • Mg—

    Si series alloy plate, the method comprising;

    hot-rolling and subsequently cold-rolling an Al—

    Mg—

    Si series alloy ingot, wherein said Al—

    Mg—

    Si series alloy ingot consists of Si;

    0.2 to 0.8 mass %, Mg;

    0.3 to 1 mass %, Fe;

    0.5 mass % or less, Cu;

    0.5 mass % or less, at least one of elements selected from the group consisting of Ti;

    0.1 mass % or less and B;

    0.1 mass % or less and the balance being Al and inevitable impurities, and wherein heat-treating for holding a rolled ingot at 200 to 400°

    C. for 1 hour or more is performed after a completion of said hot-rolling but before a completion of said cold-rolling.
