Abstract
A pressure sensor which detects a combustion pressure of an engine includes: a contact part which is in direct or indirect contact with a casing of the engine when the pressure sensor is attached to the engine; and a pressure detection unit which detects the combustion pressure and outputs a signal corresponding to the combustion pressure, wherein the pressure detection unit includes a pressure detection element which detects the combustion pressure and outputs a signal, and a circuit unit which converts the signal obtained from the pressure detection element into a signal corresponding to the combustion pressure, and the pressure detection unit is provided at a location positioned more inside the engine than the contact part when the pressure sensor is attached to the engine.
