ている。(Prior Art) With the recent trend of miniaturization and lightness of electrical equipment, there is a demand for smaller and lighter batteries. Batteries using solid electrolytes are promising to meet the expectations, and development is being focused on. In addition, as a method of making electrical equipment with a built-in solid electrolyte battery smaller and lighter and making effective use of it together with the solid electrolyte battery, an electric circuit is installed directly on the exterior of the power generating element of the solid electrolyte battery, and the chip shape is used. It has been proposed to construct an electronic control circuit together with electronic components, and to embed it in a printed wiring board.

る。(Problems to be Solved by the Invention) However, in the above-mentioned conventional method, since the electric circuit and the chip-shaped electronic component are directly formed directly on the exterior of the power generation element of the solid electrolyte battery, current flows in the electric circuit. The high heat generated thereby is applied to the solid electrolyte battery, which adversely affects the battery performance and the sealing property of the exterior. Further, the thin shape, which is also an advantage of the solid electrolyte battery, is impaired by the added thickness of the chip-shaped electronic component. Furthermore, there is a problem that it is not easy to directly mount a chip-shaped electronic component or the like directly on the exterior of the power generation element without impairing the sealing property of the solid electrolyte battery.

よい。(Means for Solving the Problem) In order to solve this problem, in the present invention, the power generation element is housed in a container made of a film or sheet formed so that the positive and negative electrode current collectors do not come into contact with each other. The container covers the power generating element so that the current collector is on the power generating element side, and extends around the power generating element to form a brim portion. It is characterized in that an electric circuit portion is formed on the portion, and that the film or sheet is joined to form a brim portion around the portion in which the power generation element is accommodated. In order to form the positive and negative electrode current collectors in a container made of a film or a sheet so that they do not contact each other, the respective electrode current collectors are arranged so as not to overlap each other, or they are stacked via an insulating layer. It may be either.
