[Problem] To provide: a sheet which is configured of ultra fine filaments of different kinds including a nanofilament having different properties (such as strength, heat resistance, hydrophobicity, filament diameter and hydrophilicity) and which has a synergistic effect of those different filaments
and a means for producing the sheet. [Solution] A sheet wherein the chemical species of the polymers that constitute filaments or the average fiber diameters of the filaments are different and wherein those filaments are mixed with each other in the same plane or respective layers of those different filaments are laminated. In this connection, one of those different filaments is a nanofilament. A means for producing the sheet.
