PROBLEM TO BE SOLVED: To provide a connection member with a sensor capable of detecting deformation of a ground insertion pipe at high sensitivity when the ground insertion pipe inserted into ground is deformed. SOLUTION: A connection member 1 with a sensor is a connection member for rigidly connecting a plurality of pipe materials 2 composing a ground insertion pipe 3 to be inserted into ground. A connection member body 5 is a hollow or solid cylindrical body and is constituted by attaching a sensor 8 using a distortion gage for detecting deformation generated in the pipe materials 2 to the outer peripheral surface or the inner peripheral surface of the cylindrical body when the cylindrical body is hollow, or attaching the sensor 8 to the outer peripheral surface when the cylindrical body is solid. The rigidity of a portion to which the sensor 8 is attached is set lower than the rigidity of the pipe material 2. Since the rigidity of the portion to which the sensor 8 is attached is lower than that of the pipe material 2, deformation generated in the ground insertion pipe 3 inserted into ground can be detected at high sensitivity by the sensor 8 attached to the portion. When the sensor 8 is attached to a groove, the sensor 8 is not brought into contact with a porous wall when inserting the pipe materials 2 into the ground, and the sensor 8 can be prevented from being damaged.
