Abstract:
A physical quantity detection device includes: a base portion; a movable portion supported by the base portion via a joint and shifting in accordance with a change of a physical quantity; a physical quantity detection element extending over the base portion and the movable portion; a first support member extending from the base portion and having a first fixing portion; and a second support member extending from the base portion and having a second fixing portion. The distance between the first fixing portion and the second fixing portion is shorter than the distance between the root of the first support member at the junction with the base portion and the root of the second support member at the junction with the base portion.
