A small-sized, simple and inexpensive electronic part protecting structure and process enabled to prevent the reconstruction of electronic parts by preventing a case from being opened. Into a plurality of through holes formed in the surface of one case, there are loosely fitted projecting pieces which are provided on the surface of the other case. The projecting pieces are provided at their leading ends with deformed portions which are made so larger than the through holes that they can not be restored. By these deformed portions, the cases cannot be easily opened to prevent the electronic parts protected between the cases from being easily extracted while preventing the reconstruction. The case having the projecting pieces is made of a metal or resin. The through holes are formed in recesses of the case surface. The cut-off the deformed portions is detected and reported. Into the through holes formed in the surface and back protecting cases, on the other hand, there is inserted a protecting pin member. This protecting pin member has a flat portion at its one end, and a deformed portion is formed at the other end after the protecting pin member was inserted. The flat portion and the deformed portion are made so larger than the through holes that they can not be restored. As a result, the cases cannot be easily opened to prevent the easy extraction of the electronic parts protected therebetween and to prevent the reconstruction.
