PROBLEM TO BE SOLVED: To provide a fastening structure of on-board mounted apparatus such as a photo-sensor or antenna to be installed on a structural member such as a honeycomb sandwich plate, etc., of a spacecraft capable of preventing transmission of vibrations from the structural member to the apparatus and contacting resulting from thermal strain, etc., and also protecting viscoelastic bodies against a load exceeding the allowable load level. SOLUTION: A fastening structure 1 to fasten a structure 3 with an apparatus to be mounted thereon 3 is composed of an insert body 5 installed on the apparatus 8 integrally, an insert attached to the structure 3 integrally and equipped with an insert table 6 having a hollow for accommodating the insert body 5, and viscoelastic bodies 4A and 4B interposed between the insert body 5 and insert table 6, wherein part of the insert body 5 abuts to part of the insert table 6 before the load applied to the viscoelastic bodies 4A and 4B attains the allowable load value for them 4A and 4B.
