Abstract: Provided is a curable siloxane composition with low dielectric constant and low dielectric loss, in which organic alkoxy silane having a silicon-based asymmetric structure and organic alkoxy silane having a silicon-based symmetric structure are included. The curable siloxane composition has low dielectric constant and dielectric loss in a high frequency range, low water absorption, excellent workability, and high copper foil peel strength, and thus physical properties suitable for application to printed circuit boards for high-frequency communication electronic devices may be provided.
