Title:
フィルム
Document Type and Number:
Japanese Patent JP6504251
Kind Code:
B2
Abstract:
The present invention provides a film having excellent heat resistance and a small difference between the permittivity at low temperatures and the permittivity at high temperatures. The present invention provides a film having a relative permittivity of 8 or more at a frequency of 1 kHz at 30°C, wherein the rate of change is - 8 to +8% as calculated from a relative permittivity A at a frequency of 1 kHz at 30°C and a relative permittivity B at a frequency of 1 kHz at 150°C according to the following formula: Rate of change % = B A / A × 100.
