Abstract:
A dielectric film includes an organic resin polymer, and an organic resin monomer. The organic resin polymer includes at least one of polyarylate and cycloolefin polymer, the organic resin monomer includes at least one of phenol monomer, sulfur monomer, and phosphorus monomer, and a total content of the organic resin monomer falls in a range of 0.01 to 7.6 parts by mass based on of 100 parts by mass the organic resin polymer.
Abstract:
There is provided an insulating material including a composite resin material comprising an organic resin (5) and minute particles (6) containing a metal element. The organic resin (5) includes a resin material including polyester as a main backbone thereof and having an alkoxy group. The minute particles (6) have an average particle size of greater than or equal to 0.5 nm but less than or equal to 50 nm. Such an insulating material is used as an insulating layer (2) of a wiring member (wiring board, covered electric wire, etc.) including a conductor (1) and the insulating layer (2) which covers the conductor (1).
Abstract:
A composite resin material (1) including: a first organic resin having a phenylene ether structure; and a second organic resin having a main skeleton composed of a polyester structure, one of the first organic resin and the second organic resin forming a continuous phase (2), the other one thereof being present within the continuous phase (2), as organic resin particles (3) having an average particle diameter of 1 µm or less.
