A non-woven fabric laminate in which surface layers (A1) and (A2), where (I) below exceeds 60 mass% and is 98 mass% or less and (II) and (III) below are 2 mass% and over to less than 40 mass%, and an intermediate layer (B), where the value of the total content by percentage of (II) and (III) below is greater than that in the surface layers (A1) and (A2), are laminated, the non-woven fabric laminate having a total weight per area of 45 g/m2 or less and a thermocompression bonding rate of 3-30%. (I) Propylene homopolymer having melting point of 140°C or higher. (II) Random copolymer comprising propylene and C2-20 α-olefin (not including C3). (III) Propylene homopolymer having melting point of less than 120°C and satisfying i-vi below. (i) [mmmm] = 20-60 mol%; (ii) [rrrr]/(1-[mmmm]) ≤ 0.1; (iii) [rmrm] ＞ 2.5 mol%; (iv) [mm] × [rr]/[mr]2 ≤ 2.0; (v) Mw = 10,000-200,000; (vi) Mw/Mn ＜ 4. |
