It increases the lifetime of the LED, to improve the workability in circuit formation and during LED mounting of the printed wiring board. Coefficient of linear expansion of 60 ppm / ℃ more than 120 ppm / ℃ insulation layer and the insulation provided on one side of the layer, and the linear expansion coefficient of 10 ppm / ℃ more than 35 ppm / ℃ than the metal foil and made of a metal material, the insulating layer other side of the formed on a surface, and the linear expansion coefficient of 10 ppm / ℃ more than 35 ppm / ℃ or less circuit portion and non-circuit portion and the insulating layer, circuit portion and non-circuit has prevented a white formed on a portion, the insulating layer the non-circuit portion of the circuit and the total sum of the partial area of less than 50% to 95% with respect to the area of the metal foil, and a linear expansion coefficient of the relationship between the linear expansion coefficient of each material insulating layer> linear expansion coefficient of metal foil> circuit portion and non-circuit of linear expansion of the partial coefficient of metal It relates to the base circuit board.
