To provide a dynamic quantity sensor element structure, enabling formation of an electrical connection part easy to be electrically connected with the outside, and which will not be influenced by the application of a high dynamic quantity.

In this dynamic quantity sensor element structure, a detection part 3 for changing and outputting an electrical signal, based on application of a dynamic quantity is nipped by a first insulator 2 and a second insulator 4. The first insulator 2, the detection part 3 and the second insulator 4 are laminated in the dynamic quantity applying direction F, and the detection part 3 has an electric connection surface 3a exposed, without being covered with the first insulator 2 on the main surface on the close contact face side with the first insulator 2.
