The present invention relates to a filter device having a water supplying rod (120) connected to a water feeding hole (110), a cylindrical filter case (130) where the water supplying rod (120) is inserted to the inside, and a water duct forming material (142) which is formed inside the filter case (130) and is inserted to the insides of an envelope-type filter unit. The water duct forming material has an effect of securing a space for water to flow, by applying a rod-shaped structure or a hollow structure to the length direction of a net or the filter having embossed upper and lower parts, thus making the upper and lower parts separated at a predetermined interval. |
