[Problem] To provide an air filter material in which spun bond nonwoven fabric and melt blown nonwoven fabric are laminated and integrated without reducing air permeability. [Solution] Spun bond nonwoven fabric comprises, as constituting filament, conjugate polyester continuous filaments having a cross-sectional shape of a nearly Y4-like shape. The continuous filament is composed of a nearly V-shape portion 6 in the nearly Y4-like shape, formed from low melting point polyester, and the other nearly + shape portion 5 therein, formed from high melting point polyester. The continuous filaments are heat-bonded with each other by the low melting point polyester. The spun bond nonwoven fabric is bonded by a powder type or spider web type hot melt adhesive agent with the melt blown nonwoven fabric.
