 note = {application/pdf, 紀要論文, Some experimental results and their brief discussions are given for the mechanism of electrets. The charges of the electret were measured by a generating voltmeter without touching their surface. For the case that the temperature of the electret was raised with a rate of 1℃/min., the noise and the external current accompanied with its decay were observed in connection with the net surface charge. Some examinations were performed by the irradiation of γ-ray and by the microscope. The electrets, which were formed without flowing current through it or formed by applying the impulsive field for only one second at various temperatures, were also investigated. In order to explain all our observations, a scheme for the formation and the decay of the electret was proposed, which was somewhat analogous to that of Gross.},
