<p>The purpose of the present invention is to easily attach a current detecting device to a cable, and to eliminate variance of current detection accuracy. A current detecting device (1) is provided with: a core module (10) having a core supporting section (11) that supports a magnetic material core (7); and an element module (20) having an element supporting section (21) that supports a hall element (8) therein. At a position of a gap portion (7B) of the magnetic material core (7) in the core module (10), a cable inserting path (12) is formed, and the element supporting section (21) is fitted in the cable inserting path (12). Both the end portions (7A) of the magnetic material core (7) and the hall element (8) are aligned by means of the first contact surface (11A) and the second contact surface (11B) of the core supporting section (11), and the third contact surface (21B) of the element supporting section (21). The two modules (10, 20) are connected to each other such that the modules can relatively move, and the element supporting section (21) is fixed by means of a lock mechanism (40) in a state wherein the element supporting section is fitted in the cable inserting path (12).</p> |
