PROBLEM TO BE SOLVED: To achieve an eddy current flaw detection probe which can improve flaw detection sensitivity while maintaining excellent passing property even in a pipeline having a bent pipe part.SOLUTION: An elastic body 101 is arranged so as to cover a coil 130 arranged in a multi coil sensor 100, and a leaf spring 102 is arranged on the elastic body 101 at a side opposite to a sensor. A spring support member 107 and a spring 103 press the multi coil sensor 100 toward a measured surface side. A member 104 connected with the sensor 100 and a member 105 connecting the member 104 and wheels 106 arranged on both sides in an X direction of the sensor 100 make the multi coil sensor 100 straightly face an inside of the pipe. A wheel 108 is arranged on the member 107 at a side opposite to the sensor. |
