Abstract: An active material layer that has a high filling rate and a higher density and is formed using a small amount of conductive additive is provided. A positive electrode active material layer includes a first carbon material and a second carbon material, which is more likely to aggregate than the first carbon material, and mixing is performed such that the weight of the second carbon material is more than or equal to 1.5 times and less than or equal to 20 times that of the first carbon material, thereby preventing the aggregation of the second carbon material and the aggregation of the first carbon material and reducing the proportion of the aggregated portions.
