Sensors and electronic devices

Abstract

To provide a sensor and an electronic device having stable characteristics.SOLUTION: According to one embodiment, a sensor includes a housing, a sensor section, and a plurality of first fixing members. The housing includes a housing base. The sensor section is surrounded with the housing. The sensor section includes a sensor base, a support portion fixed to the sensor base, a movable portion supported by the support portion, and a plurality of fixed electrodes fixed to the sensor base and facing the movable portion. A first gap is provided between the sensor base and the movable portion. The fixed electrodes are provided in n-rotational symmetry in a first plane perpendicular to a first direction from the sensor base to the support portion. The n is an integer of 2 or greater. The first fixing members fix the sensor base to the housing base. The first fixing members are provided in the n-rotational symmetry in the first plane.SELECTED DRAWING: Figure 1
