An object of the present invention is to provide a joined structure effective for preventing crack formation after thermal cycles. The joined structure has a ceramic member 1, a metal member 4 to be joined, and a metal fixed member 3 fixed to the ceramic member 1 and having an exposed face 3b exposed along the joining face 1d of the ceramic member 1. A joining layer 7 is provided between the ceramic member 1 and the metal member 4 and between the exposed face 3b of the fixed member 3 and the metal member 4. The joining layer 7 has thicker and thinner portions 7a and 7b. Alternatively, the joining layer 7 has a maximum thickness of 0.15 mm or more.
