    摘要： When an abnormality judgement section (28) judges that there is a failure of an energy inputting circuit (6), an energy inputting line (²), through which electrical energy is inputted from the energy inputting circuit (6) to a primary winding (3), is changed over to a disconnected state by output halt switching means (29). As a result, since inputting of electrical energy to the primary winding (3) is thereby halted, problems arising due to continuation of inputting electrical energy to the energy inputting circuit (6) can be prevented, even in the event of a failure of the energy inputting circuit (6), so that reliability can be enhanced.

    摘要： In a laser ignition device 1 which is mounted in an internal combustion engine 5 and at least includes a laser spark plug 10 equipped with an optical window 100 which protects an optical device from high temperature and high pressure generated in a combustion chamber and a prechamber cap 15 equipped with a cylindrical prechamber 152, a prechamber throat portion 151 that is a bottomed cylinder with a sectional area smaller than that of the prechamber, and a plurality of prechamber spray holes 150 which communicate with a combustion chamber 500 on a side of a closed end 153 of the prechamber throat portion 151, the prechamber cap 15 is arranged between the optical window 100 and the combustion chamber 500. A converging point FP is located inside the prechamber 152 to ignite an air-fuel mixture delivered into the prechamber 152, thereby jetting combustion flames from the prechamber 152 into the combustion chamber 500 to fire the internal combustion engine 5. The center axis AX F of the prechamber 152 is oriented horizontally eccentrically from the center axis AXs of the prechamber throat portion 151.
