PROBLEM TO BE SOLVED: To provide a vehicle body front structure made of long fiber reinforced polyamide resin with excellent dimension stability by reduction of anisotropy, excellent mechanical strength such as flexural modulus of elasticity and flexural strength, chemical-resistance and heat-resistance, light weight, high freedom of product design and reduced manufacturing steps. SOLUTION: In the vehicle body front structure made of long fiber reinforced polyamide resin, a content of the reinforced fiber dispersed in the structure is 30 wt% or higher and weight average fiber length is 1 mm-15 mm and the flexural modulus of elasticity of the structure part having thickness of 2 mm or more is 7 GPa or higher, the flexural strength is 200 MPa or higher and Charpy impact strength with notch is 20 kJ/m<SP>2</SP>or higher.
