A pressure bonding seal strength is high, there is no change in the seal strength due to environmental changes, the manufacturing process can be simplified, the heat seal strength is high, and there is little fuzz on the surface when the pressure seal surface is peeled off. It is to obtain a sealing sheet. A fiber mainly composed of an ethylene polymer wax having a number average molecular weight (Mn) of 200 to 20000 is provided. Moreover, the synthetic pulp containing the said fiber is provided. Furthermore, the synthetic sheet which consists of the said fiber or the said synthetic pulp, the sheet | seat for pressure bonding sealing, and a pressure bonding sheet are provided. [Selection figure] None |
