PROBLEM TO BE SOLVED: To easily feed liquid into the hole of an object to be crushed after a power probe for crushing is put into the hole of the object to improve working efficiencies, thereby expanding the conditions for performing crushing actions. SOLUTION: In the power probe 10a for crushing, a liquid feed hole 32 is formed along the center axis of a center conductor 12 to pass the liquid 6 fed from the outside through the interior of the center conductor 12 of the probe 10a, thereby discharging the liquid 6 from the exposed part 13 of the forward end of the hole 32. The probe 10a is used, for example, in such a manner as described below: the probe 10a is fitted in the hole 4 of an object 2 to be crushed, and then the inlet of the hole 4 is sealed with a sealing material 30 to feed the liquid 6 into the hole 4 through the hole 32, thereby filling the hole 4 with the liquid 6, while a positive pressure is applied onto the liquid 6 in the hole 4 until a crushing action is performed.
