ルタ積層体。[Claims for Utility Model Registration] A first filter paper element with a center hole formed therein, and a second filter paper element that also serves as a spacer and is provided with radial protrusions extending radially from a circumference surrounding the center hole. The liquid to be filtered flows in from the outer periphery of the laminated body, and the filtrate flows from the center hole through the oil passage hole formed between the joint surfaces of the first and second filter paper elements . 1. A filter laminate configured to flow out, characterized in that branch-shaped branch pieces branching from the radial protrusions of the second filter paper element are formed on the outer periphery of the radial protrusions.

Claims

[Scope of utility model registration request]

A first filter paper element having a center hole formed therein and a second filter paper element serving as a spacer provided with radial protrusions extending at equal intervals in the radial direction from a circumferential portion surrounding the center hole are alternately laminated. A filter laminate in which the liquid to be filtered flows in from the outer peripheral part of the laminate, and the filtrate flows out from the center hole through the oil passage hole formed between the joint surfaces of the first and second filter paper elements. A filter laminate, characterized in that, in the body, branch pieces branching from the radial protrusions of the second filter paper element are formed on the outer peripheral portion of the radial protrusions.
