FIBER SHEET, ELECTROSPINNING DEVICE, AND METHOD FOR MANUFACTURING FIBER SHEET
An electrospinning device includes: a plurality of nozzles that discharge a spinning solution containing a resin; and a plurality of power sources for applying charge to the solution. The power sources are connected such that different charges are applied to the solutions discharged from the nozzles...

| description | An electrospinning device includes: a plurality of nozzles that discharge a spinning solution containing a resin; and a plurality of power sources for applying charge to the solution. The power sources are connected such that different charges are applied to the solutions discharged from the nozzles, respectively. The fiber sheet is a long fiber nonwoven fabric including first fibers and second fibers that are different from the first fibers. In a histogram based on fiber diameter distributions and frequencies of the numbers of fibers, the fiber sheet has a peak where a ratio P1 of a frequency of the number of fibers of the first fibers to a frequency of the number of fibers of the second fibers is 0.01 or more and 100 or less. Alternatively, the fiber sheet has two or more peaks in the histogram, in which a ratio P2 of a frequency of the number of fibers of the first fibers at a highest peak in a range of a fiber diameter of 3 μm or less to a frequency of the number of fibers of the second fibers at a highest peak in a range of a fiber diameter of more than 3 μm is 1 or more and 1 000 or less. |
