Abstract: A toilet apparatus includes: a toilet seat disposed above a toilet bowl; an image sensor photographing an inside of a bowl of the toilet bowl; and a control unit controlling the image sensor to execute an automatic photographing mode of automatically photographing the inside of the bowl. When acquiring a user's photographing intention information indicating whether or not the user has an intention to photograph the inside of the bowl, the control unit switches between executing and stopping of the automatic photographing mode based on the acquired photographing intention information.

Abstract: A photography system includes: an authentication unit executing personal authentication of a user using a toilet bowl; and a control unit controlling an image sensor 44 to automatically photograph an inside of a bowl of the toilet bowl. The control unit 312 conducts the automatic photographing of the inside of the bowl if the personal authentication is successful and does not conduct the automatic photographing of the inside of the bowl if the personal authentication fails.

Abstract: In the case where a film having lower strength than a metal can is used as an exterior body of a secondary battery, a current collector provided in a region surrounded by the exterior body, an active material layer provided on a surface of the current collector, or the like might be damaged when force is externally applied to the secondary battery. A secondary battery resistant to external force is provided. A cushioning material is provided in a region sandwiched by an exterior body of the secondary battery. Specifically, the cushioning material is provided on the periphery of an electrode group including a positive electrode current collector, a positive electrode active material layer formed on at least one surface of the positive electrode current collector, a separator, a negative electrode current collector, and a negative electrode active material layer formed on at least one surface of the negative electrode current collector.

Abstract: The power storage device includes a positive electrode, a negative electrode, an electrolyte, and an exterior body. The positive electrode includes a positive electrode current collector and a positive electrode active material layer in contact with the positive electrode current collector. The negative electrode includes a negative electrode current collector and a negative electrode active material layer in contact with the negative electrode current collector. The positive electrode active material layer and the negative electrode active material layer overlap with each other. The positive electrode, the negative electrode, and the electrolyte are surrounded by the exterior body. When a length of the positive electrode active material layer is Py, a width of the positive electrode active material layer is Px, a length of the negative electrode active material layer is Ny, and a width of the negative electrode active material layer is Nx, Py>Px, Ny>Nx, and Ny>Py+Nx?Px are satisfied.
