<P>PROBLEM TO BE SOLVED: To provide a propylene-based composite resin composition hardly damaging the balance of mechanical properties such as rigidity and impact resistance, and moldability such as appearance and high-speed moldability while having a high filling rate of a filler, and to provide an extrusion molded product using the resin composition. Ž<P>SOLUTION: The propylene-based composite resin composition comprises ≥15 wt.% and <60 wt.% propylene-based polymer (X) composed of a component (A) insoluble in p-xylene at 25°C and a component (B) soluble in the p-xylene at 25°C, and satisfying the requirements of (i) having 100,000-1,000,000 weight average molecular weight (Mw) measured by GPC, (ii) containing ≤0.3 wt.% component insoluble in hot p-xylene, (iii) having ≥2.0 strain hardening degree (λmax) by the measurement of elongational viscosity, and (iv) having 0.5-20 g/10 min MFR (230°C, 2.16 kg load), and >40 wt.% and ≤85 wt.% filler. The extrusion molded product and the like obtained by using the resin composition are also provided. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
