Provided is a current detecting device comprising a current detecting resistor including a pair of electrodes and a resistive element; a pair of lands on which the current detecting resistor is adapted to be mounted; connection portions adapted to connect the two electrodes and the two lands, respectively; and a pair of wires connected to the two respective electrodes and adapted to detect a voltage. Positions where the two wires are connected to the two respective electrodes are located in regions on a further inner side than inner ends of the connection portions.

Current detecting device and current detecting resistor

A resistive element including a main body portion, and first and second terminal portions with different shapes that are provided at opposite ends of the main body portion in the long-side direction. At least one side portion of the main body portion in the short-side direction has a protruding portion.

Shunt resistor

Provided is a jumper or current detection resistor element having suppressed occurrence of connection defects resulting from the electromigration. The element () of the invention comprises a main body () consisting of a metal plate-shaped body, and terminal sections () provided at both ends of the main body; the terminal sections protruding from the main body, and both terminal sections provided with a mounting surface; and curved or cut surfaces (A, B, C, D, E) formed at periphery of the mounting surface. Both terminal sections are further provided with opposing surfaces at inside in direction of disposition of both terminal sections, and thickness of the opposing surfaces decreases from the mounting surface () to the main body ().
