PURPOSE: An FBG(Fiber Bragg Gratings) acceleration sensor for a multi-point measuring by series connection is provided to extract the measurement value of an acceleration sensor independently. CONSTITUTION: In an FBG(Fiber Bragg Gratings) acceleration sensor for a multi-point measuring by series connection, a mount(120) is fixed to the internal bottom of a case. A cantilever(130) has one side fixed to the top side of a mount. A weight(140) is attached to the other side of the cantilever. The FBG(Fiber Bragg Gratings) is extended in length of the cantilever and is built in the cantilever. A connecting part(160) is connectable to the optical fiber from the outside. An input connector(161) is formed together with the output connector. A connecting line is comprised of an optical fiber transmitting an optical signal. The connecting line connects the one end of the FBG to an input connector and connects the other end of the FBG to the output connector.
