A detecting device includes a detecting part configured to detect a change in an object to be detected so as to output a detection signal, an amplifying part configured to amplify the detection signal output from the detecting part to output a first amplification signal, a reference voltage supply part configured to supply a reference voltage to the amplifying part, the reference voltage being input to the amplifying part to be output as a second amplification signal, a switching part configured to switch a connection between the detecting part and the amplifying part or a connection between the amplifying part and the reference voltage supply part based on a control signal input thereto, and a comparing part configured to compare a predetermined amplification factor in the amplifying part, with an amplification factor obtained from the second amplification signal so as to output the comparison result as a comparison signal.

Detecting device and current sensor

A magnetic sensor includes a substrate, and a pattern forming region on the substrate, the pattern forming region having a substantially quadrangle shape. The pattern forming region includes a magnetic detection element pattern that includes a plurality of linear parts arranged parallel to each other at a predetermined inclination angle to two sides of the quadrangle shape, and a plurality of turning parts configured to alternately connect both end portions in a longitudinal direction of adjacent linear parts of the plurality of linear parts. The magnetic detection element pattern further includes a first pattern, and a second pattern with a resistance change ratio less than the first pattern. An area of the magnetic detection element pattern is less than an area of the pattern forming region in a plane view.
