Thermally adhesive laminated nonwoven fabric

A thermally adhesive laminated nonwoven fabric comprising a laminated nonwoven fabric in which nonwoven fabrics of the following (a) layer, (b) layer and (c) layer are integrated by heat contact bonding;

• (a) a nonwoven fabric layer consisting of one filament yarn consisting of a thermoplastic resin;
• (b) an intermediate nonwoven fabric layer having at least one extremely fine yarn having an average yarn diameter of from 1 to 3 μm consisting of the same type of thermoplastic resin as that of the (a) layer;
• and
• (c) a nonwoven fabric layer consisting of one composite filament yarn of thermoplastic resins,
• the fabric satisfying the following (1) and (2):
• (1) a difference between a melting point of the yarn forming the nonwoven fabric of the (a) layer and that of the yarn forming the nonwoven fabric of the (b) layer is 30° C. or less;
• and
• (2) the filament yarn consisting of a thermoplastic resin and forming the nonwoven fabric of the (a) layer is different from the composite filament yarn of thermoplastic resins and forming the nonwoven fabric of the (c) layer, the composite filament yarn composed of thermoplastic resins and forming the nonwoven fabric of the (c) layer contains a low melting point component, and a melting point of the low melting point component is lower than the melting point of the yarn forming the nonwoven fabric of the (a) layer by 40 to 150° C.
