<p>PROBLEM TO BE SOLVED: To provide a non-contact current detector capable of miniaturization, high in accuracy, and superior in assembling workability and productivity. SOLUTION: A current bar 1 in which a current to be detected flows is molded, for instance, in aΩshape so as to surround a certain center position, and a Hall element 2, being a magnetic detection element, is arranged in the center part. Collecting magnetic cores 3a, 3b are adhered or brought into contact with both the faces of the Hall element 2, and the current bar 1, having the Hall element 2 in the center part, is stored to a resin case 4. The current flowing in the current bar 1 is detected from the output of the Hall element 2.</p> |
