PROBLEM TO BE SOLVED: To provide a long-period fiber grating of a small size. SOLUTION: The long-period fiber grating device includes an optical fiber 11, a grooved support 12 which has grooves of a periodic structure formed therein and makes the grooves of the periodic structure abut along the axial direction of the optical fiber, a grooveless support 13 which has a flat external surface and makes the flat external surface abut on the optical fiber along its axial direction. and a tubular fiber pressure contact member 14 which holds the optical fiber pinched by the grooved support and the grooveless support, and fixes the optical fiber integrally in a pressure contact state.
