A method for manufacturing a press formed part, the method including specifying stretch flange limit strain in a metal sheet by using strain gradient in a radial direction and strain gradient in a sheet thickness direction. The strain gradient in the radial direction being directed from an end portion of the metal sheet at a time a press load is applied. The strain gradient in the sheet thickness direction being a direction of the metal sheet that intersects a loading direction. Additionally, the stretch flange limit strain satisfies the formula ϵθlim=A[a·Δϵθ/Δr+b·Δϵθ/Δt]+c, where ϵθlim represents the stretch flange limit strain in a tangential direction of the sheet edge, Δϵθ/Δr represents the strain gradient in the radial direction, Δϵθ/Δt represents the strain gradient in the sheet thickness direction, A, a, and b represent influence coefficients, and c represents the limit strain at a time the strain gradient is zero.
