Provided is a high concentration particle-containing film which is excellent in flexibility while containing a large amount of particles. The high concentration particle-containing film of the present invention comprises para-phenylenediamine, copolymerized diamine, para-based copolymerized aromatic polyamide obtained by copolymerizing paraterephthalic acid dichloride, and particles, and the copolymerized diamine contains all diamine components. And the particles are contained in an amount of 55% by volume or more, and the copolymerized diamine is 3,3 'oxydiphenylene diamine, 3,4'. 'Oxydiphenylene diamine or 4,4' oxy diphenylene diamine. |
