Electret sheet and piezoelectric detector |
| abstract |
The present invention provides an electret sheet that maintains a high generated voltage even when a large pressure is applied. The electret sheet of the present invention is characterized in that it contains a charged propylene-based resin foam sheet having an average thickness of 90 to 150 μm and an average number of bubbles in the thickness direction of 2 to 4, and the above-mentioned acrylic resin foam sheet The crosslinked propylene-based resin contains 60% by weight or more of a propylene-α-olefin random copolymer having a weight average molecular weight of 370,000 to 420,000 and a gel fraction of 30 to 50% by weight. |
