Claim 0:
1. A rubber resin material with high dielectric constant, comprising:
a rubber resin composition with high dielectric constant, and
inorganic fillers,
wherein the rubber resin composition with high dielectric constant includes:
40 wt % to 70 wt % of a liquid rubber, wherein a molecular weight of the liquid rubber ranges from 800 g/mol to 6000 g/mol, and monomers forming the liquid rubber include a styrene monomer and a butadiene monomer;
10 wt % to 30 wt % of a polyphenylene ether resin; and
20 wt % to 40 wt % of a crosslinker;

wherein, based on a total weight of the rubber resin composition with high dielectric constant being 100 phr, the inorganic fillers consist of:
100 phr to 190 phr of at least one inorganic compound selected from the group consisting of titanium dioxide, strontium titanate, and calcium titanate,
10 phr to 30 phr of alumina, and
20 phr to 60 phr of silicon dioxide;

wherein a dielectric constant of the rubber resin material with high dielectric constant is higher than or equal to 2.0.
