Abstract: A porous polyimide shaped article has a thickness in a range from 550 μm to 3,000 μm and has a relative dielectric constant of 1.8 or less and a dielectric loss tangent of 0.01 or less at 1 MHz. The porous polyimide shaped article satisfies the following formula: 1.2≤A≤1.6 wherein A represents a square root of a ratio of a pore size D84 where a cumulative percentage by number of pores from smaller sizes is 84% to a pore size D16 where the cumulative percentage by number of the pores from smaller sizes is 16% ((D84/D16)1/2) in a pore size distribution measured by mercury intrusion porosimetry.
