| 摘要 |
<p>The present invention is to provide a filter including polyvinylidene fluoride nanofibers. A polyvinylidene fluoride nanofiber non-woven fabric layer is formed on a second biocomponent substrate which is arranged on a first bicomponent substrate. And then, one surface of a third bicomponent substrate which is arranged on a fourth bicomponent substrate faces one surface of the polyvinylidene fluoride nanofiber non-woven fabric layer.</p> |
