PROBLEM TO BE SOLVED: To prevent damage of a small-sized electrical device caused by a conductive part.SOLUTION: A connection device for a small-sized electrical device has a conductive part 39 contacting with a terminal Eb protruded from an outer surface of a small-sized electrical device E, such as an electric razor, and performing electrical connection for charge or communication. The conductive part is buried in a wall surface of the periphery of the conductive part in a connection device 1, and is not protruded from a surface of the wall surface or is provided flush with the surface of the wall surface. Further, the wall surface is a convex surface with a vertex part, the conductive part is located at the vertex part, and the conductive part is also a convex surface in the same direction as the convex surface of the wall surface. |
