Busbar and electrical junction box incorporating the same

A busbar comprising:

• (a) a first busbar component serving as a busbar body and made of an electrically-conductive metal material having good spring property, the first busbar component including at least one male-terminal-connecting portion adapted to clamp a male terminal of a device connected to the first busbar component, and a power input part provided upstream of the male-terminal-connecting portion;
• and
• (b) a second busbar component made of an electrically-conductive metal material having electrical conductivity superior to that of the first busbar component, the second busbar component being connected to the first busbar component via a first section of the second busbar component in register with the power input part of the first busbar component and a second section of the second busbar component in register with a portion of the first busbar component, the portion of the first busbar component being upstream of the male-terminal-connecting portion, wherein the current flowing in the first busbar component is divided at the portion of the first busbar component.
