Battery unit and electrical device

摘要

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).

主权项

1. A battery unit having a substantially circular cylinder shape, comprising:
a flat battery in a flat shape having a first major flat surface and a second major flat surface, the flat battery having a substantially circular shape in a plan view; and a substrate fixed to one of the first major flat surface and the second major flat surface of said flat battery to face said one of the first major flat surface and the second major flat surface of said flat battery, a circuit component being mounted on a surface of said substrate facing to said flat battery, a positive electrode terminal electrically connected to a positive electrode of the flat battery and a negative electrode terminal electrically connected to a negative electrode of the flat battery being formed on a surface of said substrate that is opposite to the surface facing to said flat battery.
