PROBLEM TO BE SOLVED: To provide a pressure detector that has a spacer having elasticity disposed between a pair of detecting elements, detects the pressure applied to the detecting elements by detecting the displacement amount between the pair of plate-like detecting elements, and improves the accuracy of detecting small pressure. SOLUTION: This pressure detector includes the pair of plate-like detecting elements 13 arranged facedly, spacers 6 having electricity interposed between facing surfaces 13a of the detecting elements 13, and a detecting means for detecting the displacement amount between the facing surfaces 13a of the pair of detecting elements 13. The pressure detector detects the pressure applied to the detecting elements by detecting the displacement amount with the detecting means. The contact parts of the spacers 6 with the facing surfaces 13a of the detecting elements 13 form projecting curved surfaces of circular arc shape in the cross sectional view.
