19 Claims

1. A porous liquid crystal polymer sheet comprising:

a resin sheet having pores and containing a first component composed of a liquid crystal polymer and a second component accounting for a highest weight percentage among all components of the resin sheet except for the first component,

wherein, a region in the porous liquid crystal polymer sheet containing the second component is a first region, a region in the porous liquid crystal polymer sheet having a smaller content of the second component than the first region is a second region, and the first region has a higher compressive strength than the second region,

the second component has an average particle size smaller than an average pore size of the pores of the resin sheet, and

the second component is not inside of the pores.
