The invention provides a force detection sensor having a higher force detection property, a force sensor, a torque sensor, and a robot. The force detection sensor includes a base member having a firstsurface subjected to an external force and a second surface having a normal direction different from the first surface, and electrode fingers placed on the second surface, wherein an arrangement direction of the electrode fingers is different from the normal direction of the first surface in a plan view of the second surface. Further, the second surface includes a surface of a piezoelectric material. A constituent material of the piezoelectric material is quartz crystal. The first surface crosses an electrical axis of the quartz crystal.
