Abstract:
A particle capture filtration film with communication pores formed by anode oxidization of an aluminum material includes a small pore diameter part having communication pores formed to open to one surface of the filtration film, an intermediate pore part having communication pores to which the communication pores of the small pore diameter part are connected and that have a larger diameter than a diameter of the communication pores in the small pore diameter part, and a large pore diameter part having communication pores to which the communication pores of the intermediate pore part are connected and which have a larger diameter than a diameter of the communication pores in the intermediate pore part and are formed to open to the other surface of the filtration film.
