Abstract

An object of the present invention is to provide an electret melt-blown nonwoven fabric having high dust collection efficiency and a low pressure loss, and a filter material and an air filter obtained using the same, and the electret melt-blown nonwoven fabric of the present invention is an electret melt-blown nonwoven fabric including a polyolefin-based resin fiber, in which the nonwoven fabric contains 0.1 to 5.0 mass% of a hindered amine-based compound and 0.01 to 1 mass% of one or more kinds of metallic oxide particles including an oxide of a metal element selected from copper, cobalt, aluminum, nickel, zinc, palladium, molybdenum, and tungsten and having an average particle diameter of 500 nm or less.
