The present invention provides: a device for producing a packaged electrode capable of reducing the cycle time required for packaging an electrode between a pair of separators, capable of increasing the efficiency of producing packaged electrodes, and thus contributing to increased efficiency in producing an entire battery; and a method of producing a packaged electrode. The device (100) for producing a packaged electrode includes: a conveyance unit (200) configured to sequentially overlay the electrode (40) and the pair of separators (30) from a front end side in a conveying direction while conveying the electrode (40) and the pair of separators (30); and a joining unit (300) configured to join lateral edges of the pair of separators (30) together. In this production device, joining is performed a plurality of times from the front end side in the conveying direction, each of the joining being performed while moving the joining unit so that a speed of the joining unit relative to a conveyance speed of a workpiece W approaches zero.
