PROBLEM TO BE SOLVED: To provide a high-reliability module mounting structure in which output fluctuations due to the vibration application of a sensor element chip (sensor component) mounted on a circuit board (mounting board) are suppressed.SOLUTION: An inertia force sensor device 100 comprises: a mounting board 2 in which a component mounting face 2a is shaped such that a direction x among directions x, y is the longitudinal direction, and the length in the direction x is longer than the length in the direction y; a sensor component 1 mounted on the mounting board 2; and a housing 3 for accommodating the mounting board 2. The sensor component 1 is mounted on the mounting board 2 so that a projection shape projected onto the component mounting face 2a is like that a direction y among directions x, y is the longitudinal direction, and the length in the direction y is longer than the length in the direction x, and that the longitudinal direction of the projection shape of the sensor component 1 is not parallel to the longitudinal direction of the component mounting face 2a. |
