The invention relates to a blood filter and a filter material, wherein the blood body filter fixes the filter material in a shell, the filter material extends upward from the upper side of the body to a convex part, and the lower side forms a concave part, and the system has two parallel outer sides； thus, when a filter material raw piece cuts out a plurality of filter materials, the waste material can be effectively reduced To no, to increase the output of filter material and reduce the production cost of the blood filter.本創作係一種血液過濾器及其過濾材，其中該血液體濾器係將該過濾材固定於一外殼內，該過濾材自一本體的上側邊向上延伸有一凸部，而下側邊則向上形成有一凹部，且該本體係具有二個平行外側；如此，當一過濾材原片裁切出複數過濾材，其廢料能有效減少甚至沒有，以提高過濾材的產量，並降低該血液過濾器的製作成本。
