Document Type and Number:
Japanese Patent JP2023093099
Kind Code:
A
Abstract:
To provide a pressure detector formed by storing a piezoelectric element inserted between electrodes in a housing, the piezoelectric element being prevented from breaking.SOLUTION: The pressure detector includes: a piezoelectric element 41 for generating a charge under pressure; an electrode member 42 having a contact surface 42a facing a surface where a charge of the piezoelectric element 41 is generated; and a housing for storing the piezoelectric element 41 and the electrode member 42. In the housing, there is a gap between the contact surface 42a and the piezoelectric element 41 in a part of the contact surface 42a of the electrode member 42.SELECTED DRAWING: Figure 5
