Electrode manufacturing apparatus and method of manufacturing electrode

A method of manufacturing an electrode comprising a mixed layer disposed on one side of a current collector, wherein

• a mixture is supplied in a predetermined direction in a predetermined coating position so as to coat the mixture on one side of the current collector, thereby the mixed layer is formed by a coating head,
• a built-up mixture between the current collector and the coating head is pulled back by a mixture interrupting means in a direction opposite to a direction where the mixture is supplied, when coating of the mixture is interrupted, wherein a single valve structure pulls back the mixture when interrupting a flow of the mixture, and
• the mixture interrupting means comprises:
• a containing hole disposed in a mixture flow path,
• a shut-off valve disposed in the containing hole, and
• a valve rod being connected to the shut-off valve, and relatively moving the shut-off valve with respect to the containing hole between an open position where the shut-off valve is moved away from the containing hole so as to pass the mixture through and an interrupting position where the shut-off valve blocks the containing hole so as to interrupt the mixture.
