Claims

[Scope of utility model registration request]

In a filter element having a generally cylindrical shape as a whole, the filter element is formed by surrounding the entire circumference of an inner cylindrical core having a large number of holes, and the filter paper is folded in a pleat shape. When molding,
A filter element characterized in that a plurality of reinforcing members are arranged on the inner surface of the filter paper at parallel intervals and attached along the circumferential direction by bending and forming the reinforcing members together with the filter paper.
