Abstract
A prober interface card is provided which improves dielectric absorption characteristics between needles and signal patterns, and conductors with different potentials. A side guard conductor, having a specific height and depth, is disposed so that there is no insulating material between a needle with a connected signal pattern and an adjacent needle with its side guard conductor.
