To provide an accumulator type fuel injection pipe for a diesel engine, effective in anti-cavitation measures in a fuel injection system, and excellent in an injection property and a combustion property.

The inner diameter of other parts except for both pipe end portions or one pipe end portion of a pipe element having a connecting head portion is made to be larger than that of the both pipe end portions of the one pipe end portion, thereby providing a structure having an accumulating function. The accumulator fuel injection pipe for the diesel engine is greatly effective in the anti-cavitation measures in a non-accumulator fuel injection system. In the accumulator fuel injection system using a common rail, the common rail is downsized and made to be compact, and pulsation is suppressed at a low degree to enable high-precision injection.
