To provide a connecting structure which reduces the heating time when members are connected and suppresses degradation of connection strength.
The connecting structure includes a first member 3 which has a first face 3a, a second face 3b opposite to the first face 3a, and a through-hole 4 penetrating from the first face 3a to the second face 3b, and a second member 1 which has a base 21 having a third face 21a, the base 21 being formed opposite to the first face 3a of the first member 3, a projection 22 which is formed on the third face 21a and is put through the through-hole 4, and three extending portions 2e extending radially around the through-hole 4 from the front end of the projection 22 to the outside of the through-hole 4 on the second face 3b. The first member 3 and the second member 1 are connected in a form of being held by the third face 21a and the extending portions 2e.
