| Zusammenfassung: | Provided is a pressure sensor capable of suppressing the influence of noise on a pressure detection device as much as possible. A pressure sensor includes a pressure detection unit, a connector, and a relay board. The relay substrate has a power wiring pattern connected to a terminal pin and a wiring pin for power supply, a signal wiring pattern connected to a terminal pin and a wiring pin for signal output, and a grounding pattern for grounding a terminal pin and a wiring pin for grounding. The signal wiring pattern includes: a proximal wiring portion extending along an edge of the ground pattern; a distal wiring portion extending along the proximal wiring portion on the opposite side of the ground pattern across the proximal wiring portion; and an intermediate wiring part connecting one end of the proximal wiring part and one end of the distal wiring part, the other end of the proximal wiring part being connected to the wiring pin for signal output, and the other end of the distal wiring part being connecte |
