PROBLEM TO BE SOLVED: To detect a weak current flowing through a measurement circuit, capable of being set to detect as low as 50mV of potential difference, and detect almost all of the solder cracks in an electronic circuit. SOLUTION: The inspection apparatus for the connection conditions of an electrically connected connecting part comprises two probes, which are brought into contact with two points sandwiching the connection part and apply mechanical stress to the connection location, a means of detecting a predetermined potential difference generated between the two points by applying mechanical stress, and a means of informing the generation of the potential difference.
