POROUS RESIN SHEET FOR PIEZOELECTRIC-PYROELECTRIC ELEMENT, AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a porous resin sheet for a piezoelectric-pyroelectric element hardly lowering piezoelectric performance even under a high-temperature high-humidity environment, and to provide a method for producing the porous resin sheet.;SOLUTION: In this porous resin sheet for a piezoelectric-pyroelectric element, a glass transition point or a softening point is ≥120°C, and a water absorption is ≤0.2%.;COPYRIGHT: (C)2012,JPO&INPIT
