A battery unit provided with a flat battery and a substrate having a circuit formed thereon is provided in a compact form as a whole. The battery unit (1) includes a flat battery (2) in a flat shape having an upper surface and a bottom surface and a substrate (61) fixed to one surface of the flat battery (2). A circuit component (62) is mounted on a surface of the substrate (61) on a side of the flat battery (2), and a positive electrode terminal (68) (charging terminal) electrically connected to a positive electrode side of the flat battery (2) and a negative electrode terminal (66) (GND terminal) electrically connected to a negative electrode side of the flat battery (2) are formed on a surface of the substrate (61) on the opposite side to the flat battery (2). |
