Abstract: According to one embodiment, a MEMS element includes a first member, and an element part. The element part includes a first fixed electrode fixed to the first member, and a first movable electrode facing the first fixed electrode, a first conductive member electrically connected with the first movable electrode, and a second conductive member electrically connected with the first movable electrode. The first movable electrode is supported by the first and second conductive members to be separated from the first fixed electrode in a first state before a first electrical signal is applied between the second conductive member and the first fixed electrode. The first conductive member is separated from the first movable electrode in a second state after the first electrical signal is applied. The first movable electrode is supported by the second conductive member to be separated from the first fixed electrode in the second state.
