PROBLEM TO BE SOLVED: To provide a laser multipoint ignition device of an internal combustion engine for improving homogeneity and combustion efficiency of combustion, by generating a plurality of ignition points in a proper position in a space of a combustion chamber by using a laser device. SOLUTION: This laser multipoint ignition device is provided for igniting combustion gas filled in the combustion chamber, by making a laser beam incident on the combustion chamber 3 formed of a cylinder and a position of the internal combustion engine, and includes a laser incident end arranged on a sidewall of the combustion chamber 3, an electro-optics element 8 for changing an emitting angle of the laser beam emitted from the laser incident end with every predetermined time, and a plurality of first reflecting mirrors 9 arranged in a position corresponding to the emitting angle of the laser beam in an inner wall of the cylinder and reflecting and condensing the incident laser beam to a condensing point 5 in the combustion chamber.
