Patent ID: 8384267

Claim:
An electrostatic generator comprising: a substrate; an electrode formed on or in a surface of said substrate; an electret film provided so as to be opposed to said electrode; and an insulating film comprising a plurality of insulating film portions formed on a surface of said electrode on a side opposed to said electret film, wherein the electrostatic generator comprising the electret film is capable of generating power due to relative linear movement of the electret film and the electrode, and said electrode includes a plurality of electrode portions, each electrode portion having an insulating film portion formed thereon, and said plurality of electrode portions are physically formed in an integrated manner, a vacant gap is provided i) between adjacent ones of said plurality of electrode portions and ii) between adjacent insulating film portions; and a conductor layer provided on a surface of said electret film, wherein said conductor layer includes a plurality of conductor layer portions and said conductor layer portions are physically formed in an integrated manner.
