PROBLEM TO BE SOLVED: To provide an expansion anchor and the like capable of firmly performing anchoring at a plurality of spots from a shallow portion of an insertion hole to a deep portion.SOLUTION: An expansion anchor 10 for anchoring through a tile 5 and mortar 3, 4 to an insertion hole 8 opened in a concrete skeleton 2 comprises: a tubular anchor 21 for anchoring in the insertion hole 8 including a plurality of expansion parts 33 while distributing them in an axial direction; and an expansion cone 22 which is installed into the tubular anchor 21 and includes a plurality of cone parts 41 expanding the expansion parts 33. The plurality of expansion parts 33 are formed so as to make the inside narrower successively from a proximal end side to a distal end side, and the plurality of cone parts 41 are formed so as to make an outer diameter smaller successively from a proximal end side to a distal end side. |
