    Abstract: PROBLEM TO BE SOLVED: To prevent a product from warping and twisting due to difference of thermal expansion coefficients.SOLUTION: A printed wiring board includes: a wiring through-hole part 5 that includes a wiring through hole 5A formed across the thickness of a surface part 2A of a base material 2 and that uses an insulation material 6B having a thermal expansion coefficient different from the thermal expansion coefficient of the base material 2; and a heat expansion adjustment part 6 that includes a lower hole 6A formed in the surface part 2A of the base material 2 and that is formed by filling the lower hole 6A with the insulation material 6B. The heat expansion adjustment part 6 is arranged in cells 20, which are defined in the surface part 2A of the base material 2, in accordance with an arrangement location of the wiring through-hole part 5 in the cells 20 so that a difference of thermal expansion coefficients in vertical and horizontal directions in the cell 20 is minimum.

    Abstract: PROBLEM TO BE SOLVED: To provide a printed wiring board capable of suppressing the occurrence of stress.
    SOLUTION: A printed wiring board 11 includes an insulating layer 28 formed of an insulating material. The insulating layer 28 has a front surface formed with a conductive wiring layer 29. The conductive wiring layer 29 has a conductor 42 and a filler 44 which is embedded in the conductor 42 and has a smaller coefficient of thermal expansion than that of the conductor 42. In such a printed wiring board, the filler 44 has a smaller coefficient of thermal expansion than that of the conductor 42. As a result, the coefficient of thermal expansion of the conductive wiring layer 29 is kept smaller than that of a conductive wiring layer formed of, for example, a single conductor, thus making it possible to suppress the stress occurring in the printed wiring board 11.
