Abstract
The magnetostrictive member is formed of a single crystal of an iron-based alloy having magnetostrictive characteristics, is a plate-like body having a long-side direction and a short-side direction, and has a lattice constant of a <100> orientation in the long-side direction not larger than a lattice constant average calculated from lattice constants of <100> orientations in three directions, or the long-side direction, the short-side direction, and a direction orthogonal to the long-side direction and the short-side direction.
