Original Abstract Submitted
An angular velocity sensor includes a package, a support substrate that includes a substrate having an opening and that includes first to sixth leads extending into the opening, and an angular velocity detection element coupled to the first to sixth leads. When axes that pass through the center of gravity of the angular velocity detection element and are orthogonal to each other in a plan view are defined as a first axis and a second axis, the substrate includes a first adjustment portion that is located on one side of the first axis, that is coupled to the first to third leads, and that reduces a difference in length among the first to third leads as compared with a case where the opening has a rectangular shape, a second adjustment portion that is located on the other side of the first axis, that is coupled to the fourth to sixth leads, and that reduces a difference in length among the fourth to sixth leads as compared with a case where the opening has a rectangular shape, and a third adjustment portion that is disposed between the first adjustment portion and the second adjustment portion and that sets a length of the opening in a direction along the second axis to be larger than a length of the opening in a direction along the first axis.
