Abstract: A connection assembly includes a sensor substrate, a layer substrate coupled to the sensor substrate so as to face an upper surface of the sensor substrate, and a wire connected between the sensor substrate and the layer substrate. The sensor substrate includes first and second projections provide on the upper surface of the sensor substrate and extending in an extension direction along the upper surface of the sensor substrate. The wire has a first end sandwiched between the layer substrate and the first projection, and a second end sandwiched between the layer substrate and the second projection. The connection assembly provides reliable connection.

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 includes a first substrate, a supporter connected to the first substrate, a weight facing the first substrate, a beam of which first end is connected to the supporter and of which second end is connected to the weight, a second substrate facing the weight, and a first projection disposed on the first substrate. This senor allows effectively preventing the beam from a breakage caused by the beam twisted due to a rotation of the weight when an impact is applied to the sensor. The sensor thus can improve anti-impact property.
