FILTER, MANUFACTURING UNIT FOR FILTER, AND MANUFACTURING METHOD FOR FILTER

PROBLEM TO BE SOLVED: To provide a filter capable both of ensuring the filtration area of the filter and reducing the cost for exchange of the filter.SOLUTION: A filter (10) includes a filter and a holding member (20) which holds detachably the filter, the holding member (20) has a holding part (32) which can hold the filter in a shape in which a mountain portion and a valley portion are alternately juxtaposed along a specific direction, the holding portions (32) includes a plurality of support elements (34) which lines in a state being separated from each other in the specific direction to support each mountain portion of the filter from the rear surface side and a pair of holding elements (36) which hold the valley portion from both sides in the width direction of the filter, and the pair of holding elements (36) has a shape for holding the edges in the width direction of the valley portion, while permitting the insertion of the valley portion between both elements. 【課題】フィルタのろ過面積の確保と当該フィルタの交換にかかるコストの低減との双方が可能なろ過器を提供すること。【解決手段】ろ過器（１０）であって、フィルタと、フィルタを着脱可能に保持する保持部材（２０）とを備え、保持部材（２０）は、フィルタを山部と谷部とが特定方向に沿って交互に並ぶ形状に保持可能な保持部（３２）を有し、保持部（３２）は、前記特定方向に互いに離間した状態で並んでおりフィルタの各山部をその裏面側から支持する複数の支持要素（３４）と、フィルタの幅方向の両側から谷部を保持する一対の保持要素（３６）と、を有し、一対の保持要素（３６）は、互いの間への谷部の挿通を許容するとともに当該谷部の幅方向の端部を保持する形状を有すること。【選択図】図１
