    摘要: Provided are a surface-treated glass cloth that enables the reliability of a printed wiring board to be improved, a prepreg, and a printed wiring board. In the surface-treated glass cloth, a surface-treated layer contains a silane coupling agent, the amount of carbon attached of an adhering component of the surface-treated layer is in the range of 0.030 to 0.060% by mass, the arithmetic average height of the surface of the adhering component of the surface-treated layer is in the range of 1.0 to 3.0 nm, and the product of the amount of carbon attached of the adhering component and the arithmetic average height of the surface of the adhering component is in the range of 0.060 to 0.100.

    摘要: The surface-treated glass cloth includes a surface treatment layer on a surface, and the surface treatment layer includes: a first silane coupling agent containing at least one amine selected from the group consisting of a primary amine, a secondary amine and a tertiary amine and containing no quaternary ammonium cation; a second silane coupling agent containing at least one quaternary ammonium cation; an organic acid; and a surfactant. A total content of the first silane coupling agent and the second silane coupling agent is 0.05 to 1.20 mass% based on the total amount of the surface-treated glass cloth, a ratio of a molar content of the first silane coupling agent to a molar content of the second silane coupling agent is 1.1 to 10.0, and a content of the organic acid is 50 to 300 ppm based on the total amount of the surface-treated glass cloth.
