A wafer holder is configured of a pair of ceramic base members and conductive layers each posed between the ceramic base members. The conductive layer has a body facing a wafer and an extraction extracted from the body for external connection, wherein the body and the extraction are arranged in a single plane. Thus there can be obtained a wafer holder for use with a semiconductor manufacturing apparatus that can reduce such distortion as caused when it is heated and cooled and that can also be readily manufactured.
