An inertial sensor includes a movable element including a first movable section and a second movable section, a first detection electrode, and a first dummy electrode. The first movable section has a first section, a second section that is farther from the swing axis than the first section, and a third section disposed between the first section and second section. The first section of the first movable section has a first opening and the third section of the first movable section has a second opening. An opening ratio of the first opening to the first section of the first movable section is smaller than an opening ratio of the second opening to the third section of the first movable section.
