    Abstract: PROBLEM TO BE SOLVED: To provide a fluororesin substrate allowing sufficient suppression of warpage occurrence in reflowing and also exhibition of sufficiently excellent, high-frequency properties.SOLUTION: A fluororesin substrate is a fluororesin substrate where a dielectric layer with fluororesin being a main component is formed on a metal conductor and the dielectric layer contains hollow glass beads. The metal conductor has a surface roughness Rz (JIS B 0601-1994) of 2.0 μm or less. The fluororesin is irradiated with ionizing radiation in an irradiation dose of 0.01 to 500 kGy. The fluororesin is one, two, or more kinds of polytetrafluoroethylene (PTFE), a tetrafluoroethylene-perfluoroalkylvinyl ether copolymer (PFA), a tetrafluoroethylene-hexafluoropropylene copolymer (FEP), and a tetrafluoroethylene-ethylene copolymer (ETFE).

    Abstract: PROBLEM TO BE SOLVED: To provide a multilayered circuit board which has a low dielectric-constant interlayer insulating film and does not cause problems including a decrease in the production yield or deterioration in the transmission characteristic of a high frequency signal because its surface in contact with the interlayer insulating film has no recesses and projections, thereby being able to greatly improve characteristics such as signal transfer characteristics of multilayered circuit boards used in a package or printed circuit board, and to provide electronic equipment using the same.
    SOLUTION: A multilayered circuit board 10 comprises a plurality of wiring layers on the substrate and a plurality of insulating layers disposed between the wiring layers, wherein at least a part of the insulating layers consists of a porous insulating layer 1 containing at least one of the material selected from the porous material group consisting of a porous body, aerogel, a porous silica, a porous polymer, hollow silica, and a hollow polymer and a non-porous insulating layer 2 where at least one of its surfaces of the porous insulating layer 1 does not contain the porous material group. The electronic equipment uses the multilayered circuit board.
