1. A current detection resistor for use in detecting current flowing through an electronic component having at least two terminals separated at an interval between them, comprising:
a plate-like resistive body having a thickness; and
a first electrode and an opposite second electrode which form a stack in which the first and second electrodes are stacked in a direction of the thickness of the resistive body so as to sandwich the resistive body between them, the first electrode forming a first end of the stack in the direction of the thickness of the resistive body and the second electrode forming a second end of the stack opposite to the first end in the direction of the thickness of the resistive body,
wherein the first electrode has a first contact surface, at the first end of the stack, that is arranged in use in direct contact with the at least two terminals of the electronic component, and the first contact surface of the first electrode has a groove portion formed in alignment with the interval between the at least two terminals of the electronic component, and further wherein the second electrode has a second surface at the second end of the stack, and the second surface is devoid of any groove.
