A bonded structure is made of a first member and a second member which are bonded to each other. At least one bore having an opening is formed in a surface of the first member, and the second member is filled in the bore of the first member. The bore is defined by a diameter-increasing portion whose opening size increases in a depth direction from a surface side toward a bottom of the first member, and a first diameter-decreasing portion whose opening size decreases in the depth direction from the surface side toward the bottom. The diameter-increasing portion is formed on the surface side, and the first diameter-decreasing portion is formed on a bottom side.
