PROBLEM TO BE SOLVED: To provide a blood filter device which can be easily manufactured and can realize a sure priming operation, and its manufacturing method.SOLUTION: The blood filter device includes: an upper lid body having a blood inlet and an air outlet a lower lid body having a blood outlet and tightly joined with the upper lid body and a filter housed between the lid bodies. The blood filter device includes the filter 103 formed in a bellows shape whose outer shape is a rectangular parallelepiped with a uniform height, and spacers which are applied respectively to upper and lower parts of the bellows and provided with a plurality of pawls formed to be inserted respectively between ridge lines so that the filter 103 may not be brought into contact with each other. The filter 103 is disposed such that the bellows are positioned vertically, and is fixed, by a solidification material filled on a housing side periphery inner side, such that all the blood that has flown in from the blood inlet passes through the filter 103 and flow out from the blood outlet.COPYRIGHT: (C)2013,JPO&INPIT【課題】簡便に製造でき,確実なプライミング操作を実現可能な血液フィルタ装置およびその製造方法を提供する。【解決手段】血液流入口と空気排出口を備えた上蓋体と、血液流出口を備え上蓋体と密に接合する下蓋体と、蓋体間に収容されるフィルタとを有する血液フィルタ装置であって、フィルタ103と、高さを揃え外形が直方体である蛇腹に形成され、蛇腹の上下それぞれにあてがい、フィルタ103が互いに接触しないように稜線間それぞれに間挿される複数の爪が形成されたスペーサを具備し、フィルタ103は、蛇腹が上下に位置するように配され、ハウジング側周内側に充填される固化材によって、血液流入口から流入した血液が総てフィルタ103を通過して血液流出口から流出するように固定されたことを特徴とする。【選択図】図4
