PROBLEM TO BE SOLVED: To provide a pressure sensor capable of improving the measurement accuracy. SOLUTION: The pressure sensor is provided with a pressure receiving means, having a displacement section which is displaced, according to the pressure applied to the pressure receiving section; a piezoelectric member which receives pressure, according to the displacement of the displacement section and generates charges according to the pressure; and an electrode which is brought into contact with the piezoelectric member and takes out the charges generated by the piezoelectric member. In a space where the piezoelectric member is stored, an insulating member covering at least a part of the periphery of the piezoelectric member is arranged without going via another member in between.
