The present invention provides a forming method capable of inexpensively forming a bodily fluid purification cassette which is reduced in size as small as possible. A bodily fluid purification cassette is detachably attached to a bodily fluid purification apparatus body. The bodily fluid purification cassette includes a synthetic resin box-like body; a basic element incorporated in the box-like body; a selective element selected from a bodily fluid purification element such as a dialyzer, a plasma exchange module and an immunoadsorbent cylinder; and bodily fluid flow passages which connects the basic element and the selective element with each other. The box-like body and the bodily fluid flow passages are formed by primary molding such that a cross section of a split-type structure has a predetermined shape, and the split-type structure is integrally formed into a cassette by secondary molding. When the bodily fluid flow passages of the split-type structure are integrally formed by secondary molding, the basic element and the selective element are liquid-tightly connected to the bodily fluid flow passages. |
