Abstract

An object of the present invention is to provide a cooling structure (4) for a fuel injection valve (3) that is capable of actively releasing the heat of a nozzle portion (3B) of the fuel injection valve (3) to a low temperature portion (9) of a cylinder head (1), and thus suppressing the generation of deposits on an injection hole (7) of the fuel injection valve (3). A heat conducting member (8), which is capable of thermal conduction between the nozzle portion (3B) of the fuel injection valve (3) and the low temperature portion (9) of the cylinder head (1), is provided on an outer peripheral portion of the fuel injection valve (3).
