PROBLEM TO BE SOLVED: To provide a fuel cooling device in an internal combustion engine having an accumulator fuel injection device, which efficiently utilizes temperature characteristics of oil and water existing in an engine, and effectively reduces fuel temperature by a simple structural change. SOLUTION: In the internal combustion engine having the accumulator fuel injection device provided with an injector 2, an oil cooling means 8 catching lubricating oil dispersed from a camshaft, introducing it to a pipe 41, and cooling fuel by the lubricating oil, or a water cooling means 9 cooling fuel with the pipe 41 arranged in a channel built into the internal combustion engine, is provided to the pipe 41 connected to the outlet part of the injector 2.
