The purpose of the present invention is to provide a filter including a polyvinylidene fluoride nanofiber. According to the present invention, the filter is produced by the following steps: forming a low and a high melting point polyvinylidene fluoride nanofiber non-woven fabric layer on a first heterogeneous base material which is laminated on a first polyethylene terephthalate base material; and bonding one side of the polyvinylidene fluoride nanofiber non-woven fabric layer with one side of a second heterogeneous base material laminated on a second polyethylene terephthalate base material so that the both sides can face each other. |
