PROBLEM TO BE SOLVED: To provide a probe unit or the like which can prevent the breakdown of a measuring device due to static electricity charged on a circuit board. SOLUTION: The probe unit comprises a pair of pins 1a and 1b which come into contact with circuit interconnections 101 on the circuit board 100. A switch 1d which short-circuits the pins 1a and 1b so as to be electrically separable is installed. In a moment in which the pins 1a and 1b are brought into contact with the circuit interconnections 101, the switch 1d is closed, and the pins 1a and 1b are short-circuited. Thereby, the static electricity is made to escape to a GND, and the switch 1d is then opened so as to take a measurement.
