    Abstract: PROBLEM TO BE SOLVED: To provide a core substrate and a printed wiring board capable of suppressing the generation of stress. SOLUTION: In the core substrate 12, a core layer 13 is formed by dipping resin to a carbon fiber. For example, when the temperature of the core layer 13 rises, the resin is thermally expanded in a thickness direction of the core layer 13. The core layer 13 is sandwiched by a pair of insulating layers 22, 23. Since the glass fibers are included in the insulating layers 22, 23, the insulating layers 22, 23 have relatively high strength, thus suppressing the thermal expansion of the core layer 13 in a thickness direction of the insulating layers 22, 23 and suppressing the generation of thermal stress in the core substrate 12. On the other hand, the thermal expansion of the core layer in its thickness direction is not suppressed in a printed wiring board without any insulation layers, thus causing large thermal stress to be generated.
