PURPOSE: An optical fiber bragg grating sensor package is provided to stable maintain the angle between sensors arranging optical bragg grating sensors and be attached to the surface of the structure or be inserted into the structure. CONSTITUTION: An optical fiber bragg grating sensor package comprises a body, an optical fiber line(410), and fiber bragg grating sensors(420,420-1). The body comprises a given area of a triangular hole(440). The body has a given width of the same triangle shape to the triangular hole. The optical fiber line is arranged on the width of the body. The optical fiber bragg grating sensors are formed on the optical fiber line at an interval and an angle from the body. The number of the optical fiber bragg grating sensors is two or three. The two optical fiber bragg grating sensors are arranged along the optical fiber line arranged along the bottom side and the top side of the body at an angle of 90°.
