1. A sample holder comprising:
a pedestal made of metal; and
a Printed Circuit Board (PCB) placed on the pedestal, the PCB including a through opening that penetrates from a front surface to a rear surface of the PCB,
wherein the pedestal includes a cavity bottomed and with a top of the pedestal opened, the cavity formed at a portion corresponding to directly under the through opening on a side of the pedestal on which the PCB is placed,
as a configuration on the side on which the PCB is placed, viewed from above, a part of the cavity protruded outward from the through opening, and
wherein the through opening of the PCB is a bottomless opening in a rectangular planer shape corresponding to a rectangular planar shape of a chip to be mounted in the through opening,
the cavity formed in the pedestal is bottomed and top opened with a rectangular planer shape corresponding to a planar shape of the through opening,
the pedestal includes, at each of four corners of the rectangular-shaped cavity bottomed and top opened, a support member to support the chip when the chip is mounted thereto, and
as the configuration of the pedestal on the side on which the PCB is placed, viewed from above,
the cavity has at least a part of a region other than a region with the support member arranged, protruded outwardly by a predetermined width against at least a part of a side connecting two adjacent corners of the through opening.
