PROBLEM TO BE SOLVED: To provide a starting method for an internal combustion engine capable of realizing assured start and elimination of wasteful energy consumption by properly supplying an energy required for the start of the internal combustion engine. SOLUTION: In this starting method, fuel is injected into a cylinder 2 in an expansion stroke during the stoppage of the internal combustion engine 1 and combustion energy provided by the combustion of the fuel is utilized to start the internal combustion engine 1. Based on the state of air/fuel mixture in the cylinder into which the fuel is injected, the combustion energy Ec (t0) provided by the fuel is calculated and, based on the calculated combustion energy, a kinetic energy Ea (t1) provided to the internal combustion engine 1 by combustion is estimated. After the start of the combustion, an energy Es (t1) according to a difference between a target kinetic energy Et (t1) provided beforehand as the kinetic energy necessary for the start of the internal combustion engine 1 and the estimated kinetic energy Ea (t1) is supplied by a starter motor 17.
