PROBLEM TO BE SOLVED: To materialize a current detecting device which improves the reliability of electric connection of a magnetosensitive sensor or a primary conductor, has small size by reducing the number of components, and suppressing the variation in measurement values.SOLUTION: A current detecting device 1 includes: a magnetic core 2; a primary conductor 3; a magnetosensitive sensor 4; and a plurality of connection electrodes 5A1, 5A2, 5A3, 5B1, 5B2, 6A1, 6A2, 6A3, 6B1, and 6B2. The magnetic core 2 has an opening portion for constituting a magnetic gap 2A. Through the primary conductor 3, a magnetic uniting measured current passes, with the magnetic core 2. The magnetosensitive sensor 4 has a plurality of terminals, and is arranged on an opening portion. The plurality of connection electrode 5A1, 5A2, 5A3, 5B1, 5B2, 6A1, 6A2, 6A3, 6B1, and 6B2 are provided on a surface of the magnetic core 2. The plurality of connection electrodes includes at least the connection electrodes 5B1 and 5B2 electrically connected to the primary conductor 3, and the connection electrodes 5A1, 5A2, and 5A3 electrically and mechanically connected to the plurality of terminals of the magnetosensitive sensor 4. |
