Abstract
In a rotary probe mounted on a circuit board and used to connect a circuit of the circuit board to an external device, an outer frame has a flange portion facing the circuit board. A first lead extends along the flange portion and has a signal input terminal and is supported so as to be rotatable with respect to the circuit board. The signal input terminal is connectable to parts of the circuit of the circuit board one by one by rotating the first lead. A probing jack is connected to the first lead, and is connectable to a corresponding terminal formed on the circuit board. A ground supply terminal projects from the outer frame and is connectable to a corresponding ground terminal formed on the circuit board.
