PROBLEM TO BE SOLVED: To secure a precise pump delivery flow rate in response to various use states of combustion equipment without reducing durability of a pump, in driving control of an electromagnetic fuel pump. SOLUTION: This control device of the electromagnetic fuel pump is provided for forcibly feeding fuel toward the combustion equipment by reciprocatively operating a member for constituting a part of a fuel pressurizing chamber 6 by a variation in magnetic force by periodic current-carrying to an electromagnetic coil 5, and executes control in the direction for adapting a pump delivery flow rate by following a variation in a request fuel flow rate of the combustion equipment by changing a width of a delivery stroke, by adjusting the length of on-duty time of respective current-carrying periods in response to an operation state of the combustion equipment detected by a predetermined detecting means.
