Abstract

A connector with inhibited crosstalk for high speed signal circuits, where the connector contains an insulator formed from a resin composition obtained by incorporating 5 to 85% by weight of a ceramic dielectric powder having a dielectric constant of 30 or more determined at 25° C. and 1 MHz in a matrix resin, and the insulator is substantially homogeneous in the dielectric constant throughout the insulator.
