A process for producing a paper made essentially of a para-aromatic polyamide and having agglutinate portions, the process including subjecting to papermaking a composition comprising at least one member selected from the group of short fibers, staple fibers, pulp and polymer particles of a para-aromatic polyamide swollen with water, and then drying the resulting wet paper under pressure, preferably after removal of free water attached thereto. The para-aromatic polyamide paper obtained has heat resistance and stiffness and also has a high breaking length. This paper is thus useful as an insulating paper and can also be made useful as a material for composite materials by imparting other functions to the paper.
