Abstract: An acceleration sensor includes a weight portion having a recess section and a solid section, beam portions, a movable electrode provided on the opposite surface of the weight portion from an open surface of the recess section to extend over the recess section and the solid section, a first fixed electrode arranged at the opposite side of the movable electrode from the recess section, and a second fixed electrode arranged at the opposite side of the movable electrode from the solid section. The acceleration sensor detects acceleration using a change in capacitance between the movable electrode and the fixed electrodes caused by rotation of the weight portion. The beam portions are shifted toward the recess section such that an angle between a perpendicular line extending from a gravity center position of the weight portion to the rotation axis and a surface of the movable electrode becomes equal to 45 degrees.

Abstract: A sensor includes a sensor element, a package accommodating the sensor element in an inside of the package, a grounding electrode disposed in the package, a lid covering an opening of the package, and a lead extending from the package. The lead includes first and second portions. The first portion of the lead is electrically connected to the grounding electrode and extends along a side surface of the package with a gap provided between the first portion and the side surface. The second portion of the lead is disposed between the lid and the package and extends toward the inside of the package. In this sensor, the opening can be sealed without soldering and reliably connect the lid to the grounding electrode.

Abstract: A sensor device includes a conductive layer. The conductive layer is interposed between a first principal surface of an IC chip and a sensor element and faces the sensor element via a resin-based adhesive layer. The sensor element includes: a moving part including a moving electrode; a fixed part including a fixed electrode forming capacitance between the moving electrode and itself; a first terminal connected to the moving electrode; and a second terminal connected to the fixed electrode. The IC chip includes: a signal processor that processes a detection signal from the second terminal; a first voltage generator that generates a first voltage as an operating voltage for the processor; and a second voltage generator that generates a second voltage corresponding to the sensor element's reference potential applied to the first terminal. The conductive layer is electrically connected to the first terminal.
