摘要：
There are provided a method for suitably removing metallic foreign matter from a fluororesin and a method for producing a fluororesin with reduced metallic foreign matter, including the method for removing metallic foreign matter from a fluororesin as one of the steps.
The method for removing foreign matter from a fluororesin comprises applying a magnetic field to a fluororesin with an electromagnet while dropping the fluororesin by gravity, thereby removing metal.
