PROBLEM TO BE SOLVED: To provide a flat membrane filter medium for suspension filter which can filter suspension only by water head of a tank header by dipping the filter medium in a filtering water tank storing various sewages, causes little clogging, has superior environmental protective property dispensing with the use of a flocculant and superior filtering performance while easy in handling, can enhance filtering capacity by sucking, has superior versatility and practicality, allows stripping of suspended substances on the surface by back-washing or physical scraping using a brush or a scraper, has superior durability, maintenability and stability of the filtering performance, and is continuously operable over a long period. SOLUTION: This flat membrane filter medium for suspension has a porous layer, the layer having scrum structure formed of independent nuclear spaces serving as nuclei of porous spaces, and continuous fine spaces communicating multiple independent nuclear spaces with each another.
