NOVELTY - The method involves coating an electrode-material coating liquid on a belt-shaped electroconductive support body (1) conveyed continuously, using an extrusion system coater (4). The electroconductive support body is conveyed in contact with a part of an endless belt (6) wound between two endless-belt conveyance rollers (7) before entering into a drying process after coating the coating liquid on the support body. The support body is dried to form an electrode layer. The electrode-material coating liquid is applied on the support body for 10 to 30 seconds.    USE - Method for manufacturing a sheet-like electrode e.g. secondary battery (claimed) such as lithium ion secondary battery, for notebook personal computer, pen input personal computer, mobile personal computer, electronic book player, mobile telephone, cordless phone sub-station, pager, hand-held terminal, portable facsimile, portable copying machine, portable printer, headphone stereo, video device, liquid crystal TV, handy cleaner, portable compact disk device (CD), minidisk device, electric shaver, transceiver, electronic organizer, calculator, memory card device, portable tape recorder, radio, backup power supply. Can also be used for a coin-type battery and cylinder-shaped battery of motor vehicle, electric vehicle, motor vehicle, lighting fixture, toy, game machine device, load conditioner, timepiece and electronic flash, solar cell camera, munition, space application and medical device such as pacemaker, hearing aid and shoulder massage machine.    ADVANTAGE - The electroconductive support body is conveyed in contact with the part of the endless belt wound between two rollers before entering into drying process, thus forming the electrode layer with favorable uniformity, and hence stabilizing the quality of the secondary battery.
