Zusammenfassung:	The present invention pertains to a junction structure in which a first member and a second member are joined, wherein a hole part having an opening is formed in the surface of the first member, and the hole part of the first member is filled with the second member. Also, the hole part has; a diameter expansion section of which an opening diameter increases from the surface side toward a bottom section in the depth direction; and a first diameter contraction section of which an opening diameter decreases from the surface side toward the bottom section in the depth direction, wherein the diameter expansion section is formed at the surface side, and the first diameter contraction section is formed at the bottom section side.
