Inorganic reinforced polyamide resin composition

An inorganic reinforced polyamide resin composition containing:

• 10 to 55 mass % of a crystalline polyamide resin (A);
• 1 to 20 mass % of an amorphous polyamide resin (B);
• 40 to 70 mass % of an inorganic reinforcing material (C);
• and 0.5 to 10 mass % of a modified polyolefin resin (D) having a reactive functional group that is capable of reacting with a terminal group and/or a main-chain amide group of a polyamide resin,
• wherein a blending mass ratio between the components (A) and (D) satisfies 0.01≤(D)/(A)≤0.2,
• a blending mass ratio between the components (A) and (B) satisfies 0.05≤(B)/(A)≤0.7,
• the crystalline polyamide resin (A) is an aliphatic polyamide,
• the crystalline polyamide resin (A) contains a crystalline polyamide resin (A1) and a crystalline polyamide resin (A2) having a melting point higher than a melting point of the crystalline polyamide resin (A1) by 20° C. or more,
• a blending mass ratio between the components (A1) and (A2) is 0.1≤(A2)/(A1)≤0.5, and
• the inorganic reinforcing material (C) is glass fibers having a circular cross-section and a number average fiber length of 140 μm or more and 400 μm or less.
