Provided are a hollow fiber filter and a method for producing a hollow fiber filter whereby the pressure-resistant strength of the sealing between an end part of a casing body and an end part of a lid member has been enhanced. A hollow fiber filter (100) comprises: a hollow fiber bundle (30) a casing body (20) where the hollow fiber bundle (30) has been fixed to at least one end opening of a casing body cylinder (22) by a first sealing part (24) made of a first sealing agent, such that the hollow fiber bundle (30) has a cut open-end surface a lid member (10) provided with an inlet/outlet (12) for a fluid, the lid member being mounted onto both end parts of the casing body (20) and a second sealing part (40) comprising a packed part in which a space formed between an outer peripheral region of the cut open-end surface of the hollow fiber bundle (30) and a connection region connecting the end part of the casing body (20) and the end part of the lid member (10) has been packed with a second sealing agent, and a continuous film which extends from the packed part to at least a part of an inner surface of the lid member and has been adhered to the inner surface of the lid member.本發明係提供一種中空纖維型過濾器及中空纖維型過濾器製造方法,其提高機殼本體端部與蓋體元件端部間的密封抗壓強度。中空纖維型過濾器100係具備:中空纖維束30;機殼本體20,其透過第一封膠形成之第一密封部24將中空纖維束30固定於機殼本體用筒體22之至少一端開口部,以具備中空纖維束30切口端面;蓋體元件10,其各別裝設於機殼本體20二端部且具備流體導出入口12;及第二密封部40,其由填充部與連續外膜所組成,填充部係於中空纖維束30切口端面外圍區與機殼本體20端部、蓋體元件10端部的連結區間所形成之一空間內填充有第二封膠,連續外膜係自填充部延伸至蓋體元件內面至少一局部且附著於蓋體元件內面。10‧‧‧蓋體元件12‧‧‧流體導出入口14‧‧‧噴嘴20‧‧‧機殼本體22‧‧‧機殼本體用筒體24‧‧‧第一密封部30‧‧‧中空纖維束40‧‧‧第二密封部100‧‧‧中空纖維型過濾器
