A probe module electrically coupled to a terminal of a device under test for sending and/or receiving a signal to and/or from the device under test, includes a first substrate, a probe pin provided on the first substrate to be in contact with the terminal of the device under test, a first signal transmission pattern formed on the first substrate, the first signal transmission pattern being electrically coupled to the probe pin, with a gap formed at the first signal transmission pattern not to transmit any electric signal, and a for short-circuiting or open-circuiting the gap of the first signal transmission pattern.
