PROBLEM TO BE SOLVED: To provide a probe unit for four-terminal measurement suitable for measuring the resistance of a measured object made of a large conductor by a four-terminal measuring method. SOLUTION: A Hi-side current feeding terminal section 12, a Hi-side voltage detecting terminal section 22, a Lo-side current feeding terminal section 32, and a Lo-side voltage detecting terminal section 42 are combined to form this probe unit for four-terminal measurement. The current feeding terminal section 12 and the voltage detecting terminal section 22 are arranged separately from each other at a fixed interval on one side base section 21 made of an insulating material and are integrated into a Hi-side terminal body 11. The voltage detecting terminal section 42 and the current feeding terminal section 32 are arranged separately from each other at a fixed interval on the other side base section 41 and are integrated into a Lo-side terminal body 31. The Hi-side terminal body 11 and the Lo-side terminal body 31 allow the Hi-side voltage detecting terminal section 22 and the Lo-side voltage detecting terminal section 42 to be freely installed face to face with respect to the measured object 51.
