Summary:PROBLEM TO BE SOLVED: To provide a laminate capable of developing the original capacity of an electrostatic spun yarn nonwoven fabric, especially a filter material. SOLUTION: This laminate is constituted by integrally bonding a nonwoven fabric, which is manufactured by an electrostatic spinning method and an air permeable sheet by an adhesive and the penetration depth of the adhesive from the surface of a nonwoven fabric piece in the thickness direction of the adhesive is set to 40% or below of the thickness of the nonwoven fabric. Further, it is preferable that the area occupied by the adhesive on the surface of the nonwoven fabric piece is preferably 10-70% of the surface area of the nonwoven fabric piece. The filter material comprises the laminate. COPYRIGHT: (C)2007,JPO&INPIT
