Summary:PROBLEM TO BE SOLVED: To provide a filter improved in dimensional stability and comprising a meta-type fully-aromatic polyamide fiber. SOLUTION: The filter includes the meta-type fully-aromatic polyamide fiber. The meta-type fully-aromatic polyamide fiber is characterized in that the residual amount of a solvent remaining in the fiber is 1.0 mass% or below, its dry heat shrinkability at 300°C is 3.0% or below and its breaking strength is 3.0 cN/dtex or above.
