Abstract
A probe for electrical test comprises a probe body having a base end attached to a support base plate through a solder and a front end continuous with said base end and a surface layer showing a conductivity higher than that of the probe body and a solder wettability higher than that of the probe body and extending on the surface of the probe body from the base end to the front end. In the vicinity of the base end of the surface layer, a shield region having a smaller solder wettability than that of the surface layer is formed across the surface layer.
