To provide a palette for conveying a substrate, capable of preventing inverse fitting or wrong fitting of a connecter.

A pressing plate 10 is fixed in such position and orientation as a plurality of female second connecters can be separately engaged with a plurality of male first connecters mounted on a wiring board 50. The wiring board 50 is pressed toward a palette body 2 by the pressing plate 10 through the first connectors engaged with the second connectors. If any one of second connectors does not engage with a corresponding first connector, the pressing plate 10 is not allowed to be entirely engaged with the palette body 2. Since the pressing plate 10 cannot be entirely engaged if any one of the plurality of first connectors mounted on the wiring board 50 accompanies wrong fitting or inverse fitting, an operator is surely made to know occurrence of wrong fitting or inverse fitting.
