PURPOSE:To enable the inspection of an output signal in a burn-in state from the outside with good efficiency, by mounting a signal retrieving connector for retrieving the input signal or output signal of a device to be tested to the outside of a board at this side of the board. CONSTITUTION:A monitor signal retrieving connector 10 is mounted to this side part of a board main body 1, for example, to the protruded leading end edge part on said board main board 1. In the burn-in test of a device 5 tested by a burn-in apparatus having said board main body 1, the input signal of the device 5 tested or the output signal thereof in an burn-in state can be retrieved to the signal waveform monitor apparatus outside the board main body 1 through the monitor signal retrieving connector 10 and a signal waveform can be inspected with good efficiency.
