Abstract: A capacitive sensor includes at least one support member, a first anchor member, a second anchor member, a first connecting member, and a second connecting member. The first anchor member is fixed to only the first substrate of the first substrate and the second substrate. The second anchor member is fixed to the first substrate and the second substrate. The first connecting member is separate from the first substrate and the second substrate and connects the first anchor member to the movable member. The second connecting member connects the first anchor member to the second anchor member. The first connecting member includes a first elastic member which is elastically deformable. The second connecting member includes at least one second elastic member which is separate from the first substrate and the second substrate and which is elastically deformable.

Abstract: A physical quantity sensor includes a substrate, an anchor portion, a surrounding portion, a detecting element, a moving portion, and a beam portion. The anchor portion is formed on the same side as a principal surface of the substrate and fixed to the substrate. The surrounding portion is formed on the same side as the principal surface of the substrate and surrounds the anchor portion. The detecting element detects a physical quantity as a target of detection. The moving portion is provided with at least a part of the detecting element, formed on the same side as the principal surface of the substrate, and connected to the surrounding portion. The beam portion is formed on the same side as the principal surface of the substrate and connects the anchor portion and the surrounding portion together.

Abstract: An anchor member supports a frame-shaped member. A first input electrode is located outside the frame-shaped member and separate from the frame-shaped member and fixed to a substrate. A second input electrode includes an electrode portion located outside the frame-shaped member and connected to the frame-shaped member. The second input electrode is displaceable in a prescribed direction. A first reference electrode is inside the frame-shaped member and fixed to the substrate. A second reference electrode includes an electrode portion located inside of the frame-shaped member and connected to the frame-shaped member. The second reference electrode is displaceable in the prescribed direction. In the structural component, the first input electrode and the electrode portion of the second input electrode are located between the frame-shaped member and a weight member in the prescribed direction in plan view in a thickness direction defined with respect to the substrate.
