Claims8
A porous membrane comprising:
- a first surface and a second surface;
- and
- a plurality of through pores,
- wherein each of the plurality of through pores comprises a first pore portion and a second pore portion,
- wherein the first pore portion has one end open at the first surface of the porous membrane, has a first particle positioned therein, and has a horizontal axis of a minimum length of 0.1 times or more and 1.5 times or less than a diameter of the first particle and of a maximum length of 1.0 times or more and 1.9 times or less than the diameter of the first particle in a longitudinal section of the first pore portion,
- wherein the second pore portion has one end connected to the first pore portion and another end open at the second surface of the porous membrane, has a second particle, which specifically reacts with the first particle, positioned therein, and has a horizontal axis of a minimum length of 0.1 times or more and 1.5 times or less than a diameter of the second particle and of a maximum length of 1.0 times or more and 1.9 times or less than the diameter of the second particle in a longitudinal section of the second pore portion, and
- wherein the horizontal axis of the first pore portion and the horizontal axis of the second pore portion have different lengths from each other in the longitudinal section of the first pore portion and the longitudinal section of the second pore portion.
