To provide a positive electrode manufacturing apparatus in which electrode cracking is suppressed even when high linear pressure pressing is performed and turbidity between a positive electrode material and an end member is suppressed.SOLUTION: In a positive electrode manufacturing apparatus that applies a positive electrode material and an end member to a positive electrode foil while conveying the positive electrode foil, an end member discharge port is provided on the downstream side of a positive electrode material discharge port in the transport direction of the positive electrode foil, and in the width direction, a space is provided between the positive electrode material discharge port and the end member discharge port, and a partition is formed between a positive electrode material flow path and an end member flow path.SELECTED DRAWING: Figure 1 【課題】高線圧プレスを行っても電極割れが抑制され、かつ、正極材と端部材との混濁が抑制される正極の製造装置を提供する。【解決手段】正極箔を搬送しながら正極材及び端部材を該正極箔に塗工する正極の製造装置において、端部材吐出口は正極材吐出口よりも正極箔の搬送方向の下流側に設けられており、幅方向において、正極材吐出口と端部材吐出口との間には間隔が設けられており、正極材流路と端部材流路との間には間仕切りが形成されている。【選択図】図１
