  • Patent number: 11227721
    Abstract: An electronic component includes an element body, an external electrode, and a resin film having electrical insulation properties. The element body includes a principal surface and a side surface adjacent to the principal surface. The external electrode includes a first electrode portion disposed on the principal surface and a second electrode portion disposed on the side surface. The resin film is disposed on the principal surface and is in contact with the principal surface. Each of the first electrode portion and the second electrode portion includes a conductive resin layer disposed on the element body. A conductive resin layer included in the first electrode portion is disposed on the resin film and is in contact with the resin film.

  • Publication number: 20150232653
    Abstract: The invention offers a heat-resistant flame-retardant rubber composition having low adhesiveness even in an uncrosslinked state, an insulated wire having an insulating covering composed of the heat-resistant flame-retardant rubber composition, and a rubber tube composed of the foregoing heat-resistant flame-retardant rubber composition. The heat-resistant flame-retardant rubber composition is formed by mixing 10 to 100 mass parts of an inorganic filler with 100 mass parts of a mixture produced by mixing (A) a vinylidene fluoride-hexafluoropropylene-based copolymer rubber and/or a vinylidene fluoride-hexafluoropropylene-tetrafluoroethylene-based copolymer rubber and (B) polyvinylidene fluoride at a mass ratio of 90:10 to 60:40. The insulated wire has an insulating covering composed of the rubber composition and irradiated with ionizing radiation. The rubber tube is composed of the foregoing heat-resistant flame-retardant rubber composition and irradiated with ionizing radiation.
