摘要: The disclosure has a configuration including: a supporting substrate having a cavity; at least one bridge section extending directly above the cavity and having at least one end supported by the supporting substrate and an other end; and a thermopile wiring formed in the bridge section and including hot junctions in the bridge section and cold junctions directly above the supporting substrate, the hot junctions being connected to the cold junctions. The bridge section is provided with: at least one breakage detection wiring for detecting breakage of the bridge section; and at least one heater wiring. The breakage detection wiring is wired along the thermopile wiring. The heater wiring is wired such that part of the heater wiring is in an area between the other end of the bridge section and the hot junctions.

摘要: An infrared sensor includes an infrared detecting device, a lens, a member, a gap and a spacer. The lens is disposed above the infrared detecting device. The member forms an external surface and includes a first opening having a maximum internal diameter. The gap is disposed between the member and the lens. The spacer is disposed between the member and the lens so as to form the gap, and that is directly contact with lens. The spacer has a circular inner periphery, in planar view, which has a larger internal diameter than the maximum internal diameter of the first opening of the member.

摘要: 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).

摘要: An infrared sensor, which achieves a low manufacturing cost, or has high sensitivity, or in which an increase in heat capacity is reduced, is provided. The infrared sensor includes a first infrared absorbing portion, an infrared sensing portion for sensing infrared rays based on infrared rays absorbed by the first infrared absorbing portion, and a plurality of protrusions including metal and disposed apart from each other on a surface of the first infrared absorbing portion. Since an absorption rate of infrared rays is improved, sensitivity can be improved, or an increase in heat capacity can be reduced.
