PURPOSE: To provide printed circuit board supporting structure, its loading device and a robot hand, which reduces the deflection during heat treatment substantially for improving the quality after the heat treatment. CONSTITUTION: The printed circuit board supporting structure comprises a gondola 2, printed circuit board receivers 1 which are provided in multi stages in the gondola 2 and each of which supports a printed circuit board W at two points, and the robot hand 3, which is provided with a body section, which when inserted into the space between the board W, extends to the center section Wc between the board receivers 1 in the insertion direction, and an overhanging section, which is located in a space section between the boards W and extends to the position of the board receiver 1 in a lateral direction X so that the robot hand 3 does not interfere with the board receiver 1 in the insertion direction.
