Kind Code:
A
Abstract:

To provide a low dielectric constant polyimide foam which is useful as a substrate for electronic parts.

In this low dielectric constant polyimide foam, the dielectric rate is within a range of 1.5 to 2.8. Although a means to make the dielectric constant within the range is not specified particularly, achievement becomes easy by controlling the average pore size of the foam.
