PROBLEM TO BE SOLVED: To provide a pop-up coffee paper filter with excellent storage, design and functional properties in which a coffee paper filter can be taken out easily and sanitarily one after another by letting standing an upper edge of a next filter at a taking out window by picking upward a part of the coffee paper filter from, for example, a box containing the coffee paper filters. SOLUTION: A continuous coffee paper filter provided with perforations or seams which leave a part of paper so as to be cut with applying an adequate tension is folded and stored in a box, etc., having an taking out window on upper side. When pulled upward out of the taking out window, the filter is taken out one after another separated at a perforation or a seam as an outer edge part (about 1/3 of an arc shaped part) of the next filter is picked up.
