Abstract: To utilize a result of image analysis, an image analysis apparatus 100 includes an analysis result acquisition unit 110 and a counting unit 111. The analysis result acquisition unit 110 acquires analysis information being information acquired by analyzing a still image and including an appearance attribute to which a person included in the still image belongs. The counting unit 111 counts, for each appearance attribute, the number of persons belonging to the appearance attribute in the still image by using the analysis information, and generates counting information indicating a result of the counting in units of still images.

Abstract: One of the objects of the present invention is to suppress a short circuit due to metal deposition in an insulating layer in a secondary battery in which a positive electrode and a negative electrode are disposed to face each other via the insulating layer. The secondary battery comprises a battery element including at least one positive electrode 11 and at least one negative electrode 12, and a casing that seals the battery element together with an electrolyte. At least one of the positive electrode 11 and the negative electrode 12 comprises a current collector, an active material layer formed on at least one surface of the current collector, and an insulating layer 112 formed on the surface of the active material layer. The electrolyte comprises an electrolyte component and a crosslinked gelling agent. The gelling agent exists at least between the active material layer of the positive electrode 11 and the active material layer of the negative electrode 12, and the ratio Rg of the gelling agent to 100% by mass of the electrolyte component in between the active material layer of the positive electrode 11 and the active material layer of the negative electrode 12 is 0
