Array probe jig

An array probe jig capable of being mounted on an array probe that includes a plurality of coil modules each including an excitation coil and a detection coil, and a coil holder that holds the plurality of coil modules so as to be arranged on the same plane and that is formed of an elastically deformable material, the array probe jig comprising:

• a bag body which has a pressing surface that presses the array probe against an inspection target location, and which is formed of an elastic material capable of being expanded by a fluid filling an interior of the bag body;
• a supporting member that supports the bag body;
• an elastic member that is disposed adjacent to the bag body and that biases the array probe in a direction toward the inspection target location;
• and
• a pressing member that is detachably provided at a tip of the elastic member and that forms a part of the pressing surface for pressing the array probe against the inspection target location, wherein
• a surface of the pressing member facing the array probe side is inclined to intersect a central axis of a coil spring serving as the elastic member in a state of not being orthogonal to the central axis.
