<P>PROBLEM TO BE SOLVED: To provide a battery lid with an electrode terminal, capable of preventing a leak current flow. <P>SOLUTION: The battery lid with the electrode terminal comprises: a lid member having a bottomed and cylindrical-shaped protrusion provided by processing a lid material, and having an external face and an internal face; an electrode connection terminal disposed on the internal face side of the lid member; an external connection terminal electrically connected to the electrode connection terminal; an internal insulation member disposed between the internal face of the lid member and the electrode connection terminal, and having a convex portion or a concave portion; and an external insulation member disposed between the external face of the lid member and the external connection terminal, and having a convex portion or a concave portion. The bottomed and cylindrical-shaped protrusion has a cylindrical portion, and is engaged with the concave portion of the internal insulation member at the outside of the protrusion, and is engaged with the convex portion of the external insulation member at the inside of the cylindrical portion of the protrusion. Alternatively, the bottomed and cylindrical-shaped protrusion is engaged with the concave portion of the external insulation member at the outside of the protrusion, and is engaged with the convex portion of the internal insulation member at the inside of the cylindrical portion of the protrusion. <P>COPYRIGHT: (C)2012,JPO&INPIT |
