Abstract
Provided is a current detection device, which is capable of measuring a large current with a high degree of accuracy and reliability. The current detection device comprises a first wiring member consisting of a highly conductive material, a second wiring member consisting of a highly conductive material, and a resistance body consisting of a metal material having a smaller temperature coefficient of resistance than the highly conductive materials used in the wiring members. The first wiring member and the second wiring member are welded to the resistance body, and the second wiring member is longer than the first wiring member. The second wiring member has a plurality of bent portions. The plurality of bent portions includes portions bent to horizontal direction and portions bent to vertical direction. Voltage detection terminals are formed in the vicinity of the resistance body on the first and second wiring members.
