Thereby improving the production yield of power storage devices such as lithium ion batteries. Means for Solving the Problems In order to solve the above problems, in a power storage sheet manufacturing apparatus, a dispenser, a first slit die coater, and a second slit die coater are sequentially disposed in a first direction in which a current collecting foil travels. The dispenser is formed by applying a plurality of first insulating materials in a slurry form to a surface of a current collecting foil, the first slit die coater applying a slurry-like cathode material to a surface of the current collecting foil, A second insulating material in slurry form is applied to the upper surface of the cathode material. Further, the plurality of first insulating materials are applied apart from each other in the second direction orthogonal to the first direction, and the cathode material is applied between the first insulating films adjacent to each other in the second direction. |
