POROUS RESIN SHEET FOR PIEZOELECTRIC/PYROELECTRIC ELEMENT AND PIEZOELECTRIC/PYROELECTRIC ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a porous resin sheet for a piezoelectric/pyroelectric element capable of increasing a signal generated apparently from an original value while keeping the thickness of a module thin, and to provide a piezoelectric/pyroelectric element.;SOLUTION: The porous resin sheet 2 has protrusions 3 of 10-800 μm high on the surface where a signal electrode 4 is laminated. Total area of the protrusions 3 is equal to 5-30% of the plane area of the porous resin sheet 2.;COPYRIGHT: (C)2013,JPO&INPIT
