ELECTRET STRUCTURE AND METHOD FOR MANUFACTURING SAME, AND ELECTROSTATIC INDUCTION-TYPE CONVERSION ELEMENT |
| 摘要 |
An electret-structure encompasses a fluorine-resin film 21, an electrode 22 formed on one surface of the fluorine-resin film 21, and a silica layer 21 formed on another surface of the fluorine-resin film 21. The silica layer 21 is implemented by a plurality of island-shaped silica regions 201 for covering the fluorine-resin film 21 in a topology such that the island-shaped silica regions 201 are isolated from each other. And negative charges are deposited on the island-shaped silica regions 201. The static-induction conversion element with the electret-structure 1 can be mounted on a substrate by reflow-process through Pb-free solder. |

1. An electret-structure comprising:
a fluorine-resin film; an electrode formed on one surface of the fluorine-resin film; and a silica layer formed on another surface of the fluorine-resin film, wherein the silica layer is implemented by a plurality of island-shaped silica regions for covering the fluorine-resin film in a topology such that the island-shaped silica regions are isolated from each other, and negative charges are deposited on the island-shaped silica regions. |
