PROBLEM TO BE SOLVED: To provide a filter having a high collection rate and low pressure loss and using a nanofiber, and having intensity.SOLUTION: The filter having nanofiber is produced by: spraying a binder of giant molecule made into a nanofiber state to a base material surface of a nonwoven fabric which is rougher than a produced filter; spraying a nanofiber of giant molecule spun from a nanofiber production part so that thickness of the nanofiber becomes uniform; heating and compressing the base material, the nanofiber, and the binder for jointing, in which heating and compression are executed at predetermined temperature and pressure so that the binder does not become a film-state and does not occlude meshes of the nanofiber; and integrating the base material and the nanofiber. |
