NOVELTY - The apparatus (10) has a heating power control part for controlling heating power of a heating apparatus i.e. hot-air nozzle (70) such that the heating power of the heating apparatus is made small when a heat transfer value computed by a heat transfer value calculation part is better rather than a target heat transfer value and the heating power of the heating apparatus is enlarged when the heat transfer value computed by the heat transfer value calculation part is worse than the target heat transfer value compared by a heat transfer value comparison part based on heat transfer condition.    USE - Apparatus for manufacturing an electrode plate e.g. positive electrode plate and negative electrode plate, of a battery i.e. lithium ion secondary battery, utilized in a vehicle e.g. hybrid vehicle and electric vehicle, and an electronic device e.g. mobile telephone and personal computer.    ADVANTAGE - The heating power control part controls the heating power of the heating apparatus such that the heating power of the heating apparatus can be made small when the heat transfer value computed by the heat transfer value calculation part is made better rather than the target heat transfer value and the heating power of the heating apparatus can be enlarged when the heat transfer value computed by the heat transfer value calculation part is made worse than the target heat transfer value based on the heat transfer condition, so that temperature of an electrode plate can be kept constant by considering the heat transfer condition to a work-piece and thermally-conductive condition inside the work-piece, thus performing temperature control adapted to change of dried condition of the work-piece and preventing quality of the electrode plate that does not turn into desired quality.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing a battery electrode plate.
