Abstract

A MEMS element includes: a substrate; a first electrode formed above the substrate; and a second electrode having a support portion and a beam portion, the support portion being formed above the substrate, the beam portion extending from the support portion, being formed in a state of having a gap between the first electrode and the beam portion, and being capable of vibrating in a thickness direction of the substrate. The width of the beam portion decreases with distance from a base of the beam portion toward a tip of the beam portion. The central length of the beam portion is larger than the lengths of ends of the beam portion. The width of the base of the beam portion is larger than the central length of the beam portion.
