摘要： An objective is to improve the mechanical strength and the durability of a current collector for a non-aqueous electrolyte secondary battery and to allow an active material layer to be efficiently carried on the surface of the current collector with high adhesion. This objective is achieved with the use of a pair of processing means being disposed such that the surfaces thereof are in press contact with each other to form a press nip for passing a sheet material therethrough and having a plurality of recesses formed on the surface of at least one of the processing means, by passing a metallic foil for current collector through the press nip between the processing means to perform compression, thereby to form a plurality of projections on at least one surface of the metallic foil for current collector by partial plastic deformation associated with the compression.

摘要： A laser beam 21 outputted by a laser oscillator 3 is collected by a machining head 4, so that the surface of a roller 2 is irradiated with the laser beam. An encoder 5c outputs a signal in accordance with a rotational position of the roller 2. A control portion 24 controls the laser oscillator 3 to irradiate the roller 2 at the same spots on the surface with the laser beam 21 per rotation of the roller 2, the irradiation being repeated a plurality of times, thereby forming recesses in the surface of the roller.
