  "textContent": "Provided is a means which is capable of achieving satisfactory rate characteristics, while sufficiently making use of a high capacity that is a characteristic of a solid solution positive electrode active material in an electrical device such as a lithium ion secondary battery having a positive electrode which uses a solid solution positive electrode active material. [0002] An electrical device having a power generating element which includes a positive electrode where a positive electrode active material layer containing a positive electrode active material is formed on a surface of a positive electrode current collector, a negative electrode where a negative electrode active material layer containing a negative electrode active material is formed on a surface of a negative electrode current collector, and a separator, in which the coating amount of the negative electrode active material layer is set at 4 to 11 mg/cm, the negative electrode active material layer contains a negative electrode active material represented by Formula (1), the positive electrode active material layer contains a positive electrode active material (a solid solution positive electrode active material) represented by Formula (2), and in that case, as a solid solution positive electrode active material to be contained in the positive electrode active material layer, a material represented by Formula (3) and having a particle surface that is provided with a certain amount of coating layer which is formed of an oxide or complex oxide of a metal that is selected from the group consisting of Al, Zr and Ti is used.",
