Abstract: A component sensor detects a fluid component with improved accuracy. The component sensor includes tube (3) including tube side (4) that permits inflow of fluid (2), substrate (5) provided to tube (3), first protrusion (6) provided at one end of substrate (5), second protrusion (7) provided at another end of substrate (5), light emitter (9) that emits infrared light (8) toward first protrusion (6), and light receiver (10) that receives infrared light (8). Infrared light (8) entering substrate (5) through first protrusion (6) experiences total reflection inside substrate (5) and exits through second protrusion (7) to head for light receiver (10). Tube side (4) includes two through holes (13) that each extend between an interior and an exterior of tube (3). Substrate (5) is inserted into through holes (13) with a central part of substrate (5) being inside tube (3) and with the one end and the other end of substrate (5) that are respectively provided with first protrusion (6) and second protrusion (7) being outside tube (3).

Abstract: A magnetic sensor according to the present disclosure includes a plurality of magnetoresistance pattern portions that forms a bridge circuit. Each of the plurality of magnetoresistance pattern portions includes a first resistance portion and a second resistance portion that are connected together in series. In each of the plurality of magnetoresistance pattern portions, the first resistance portion and the second resistance portion are spaced from each other in a first direction by a distance that is one half as long as a cycle of magnetization of a detection target. In each of the plurality of magnetoresistance pattern portions, the first resistance portion and the second resistance portion are symmetric to each other with respect to a line when viewed in plan in a third direction.

Abstract: In a magnetic sensor according to the present disclosure, each of a plurality of magnetoresistance pattern portions includes a first resistance portion and a second resistance portion that are connected together in series. One of two resistance portions connects a first wiring portion and a second wiring portion of a first wiring pattern portion. The other of the two resistance portions connects a first wiring portion and a second wiring portion of a second wiring pattern portion. The two resistance portions are included in the plurality of first resistance portions and the plurality of second resistance portions and located at both ends in a first direction.
