Zusammenfassung:	PROBLEM TO BE SOLVED: To improve mechanical strength, to reduce as total basis weight, to lower pressure loss, to improve dust collecting efficiency and to secure a sufficient dust collecting volume even under a low air capacity in a filter for an electric vacuum cleaner using electret non-woven fabric. SOLUTION: This filter for the vacuum cleaner is formed by successively laminating the outer layer nonwoven fabric of the basic weight 12-35 g/m2 for which thermoplastic synthetic fibers whose official regain is 1.0% or less are thermally melt-stuck to each other, the electret nonwoven fabric of the basis weight 5-20 g/m2 and the inner layer nonwoven fabric of the basis weight 12-35 g/m2 for which the thermoplastic synthetic fibers whose official regain is 1.0% or less are thermally melt-stuck to each other. The total basis weight of 35-55 g/m2, the stiffness of T0.6 mN or less and the stiffness of Y0.3 mN or less are attained.
