Abstract: Provided is a variable-wavelength surface emission laser having a wide wavelength variation range. A partial region of a thin-plate substrate (22) and a movable mirror (20), the partial region being positioned between an air gap (G1) and a movable gap (G2), can move toward the air gap (G1) side or the movable gap (G2) side.
