A thermally adhesive laminated nonwoven fabric that is 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) layer consisting of at least one filament yarn nonwoven fabric layer composed of a thermoplastic resin; (b) layer consisting of at least one extremely fine yarn nonwoven fabric layer composed of the same type of thermoplastic resin as that of the (a) layer; and (c) layer consisting of at least one composite filament yarn nonwoven fabric layer composed of a thermoplastic resin, and that satisfies the following conditions to: the difference between the 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 Kelvin or less; the amount (wt.%) of the extremely fine yarn forming the nonwoven fabric of the (b) layer is from 5 to 50 wt.% based on the yarn amount of the whole laminated nonwoven fabric, and is 1 g/m 2 or more; the average yarn diameter of the extremely fine yarn forming the nonwoven fabric of the (b) layer is from 1 to 3 μm; and the composite filament yarn composed of the thermoplastic resin and forming the nonwoven fabric of the (c) layer contains a low melting point component, and the melting point of the low melting point component is lower than that of the yarn forming the nonwoven fabric of the (a) layer by 40 to 150 Kelvin. (a) layer consisting of at least one filament yarn nonwoven fabric layer composed of a thermoplastic resin; (b) layer consisting of at least one extremely fine yarn nonwoven fabric layer composed of the same type of thermoplastic resin as that of the (a) layer; and (c) layer consisting of at least one composite filament yarn nonwoven fabric layer composed of a thermoplastic resin, and that satisfies the following conditions to: the difference between the 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 Kelvin or less; the amount (wt.%) of the extremely fine yarn forming the nonwoven fabric of the (b) layer is from 5 to 50 wt.% based on the yarn amount of the whole laminated nonwoven fabric, and is 1 g/m 2 or more; the average yarn diameter of the extremely fine yarn forming the nonwoven fabric of the (b) layer is from 1 to 3 μm; and the composite filament yarn composed of the thermoplastic resin and forming the nonwoven fabric of the (c) layer contains a low melting point component, and the melting point of the low melting point component is lower than that of the yarn forming the nonwoven fabric of the (a) layer by 40 to 150 Kelvin. the difference between the 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 Kelvin or less; the amount (wt.%) of the extremely fine yarn forming the nonwoven fabric of the (b) layer is from 5 to 50 wt.% based on the yarn amount of the whole laminated nonwoven fabric, and is 1 g/m 2 or more; the average yarn diameter of the extremely fine yarn forming the nonwoven fabric of the (b) layer is from 1 to 3 μm; and the composite filament yarn composed of the thermoplastic resin and forming the nonwoven fabric of the (c) layer contains a low melting point component, and the melting point of the low melting point component is lower than that of the yarn forming the nonwoven fabric of the (a) layer by 40 to 150 Kelvin.
