Porous polyimide molded body and method for producing porous polyimide molded body |
| abstract |
The present invention provides a polyimide molded body having improved tensile strength and suppressing occurrence of in-plane unevenness of relative dielectric constant. In a pore diameter distribution measured by a mercury intrusion method and having a film thickness of 550 μm or more and 3000 μm or less, the fineness relative to the pore diameter D 16 when it becomes 16% accumulated from the small diameter side of the pores on the basis of several numbers. The square root ((D 84 / D 16 ) 1/2 ) of the ratio of the pore diameter D 84 when it becomes 84% accumulated from the small diameter side of the pore is 1.2 or more and 1.6 or less, and the relative dielectric constant at 1 MHz Is a porous polyimide molded body having a dielectric loss tangent of 0.01 or less.
