[0058] In order to prevent the mixed gas pressure in the cylinder head mounting hole 101 from being too high, it is necessary to set a vent hole 121 in the ignition coil device to discharge the mixed gas in the cylinder head mounting hole 101. However, the setting of the vent hole 121 will result in poor waterproofness of the ignition coil device, and even cause water to enter the cylinder head mounting hole 101.

[0059] To this end, the following combination Figures 1 to 6 The specific implementation mode of the utility model is described.

[0060] Figures 1 to 4The utility model provides a high-voltage package 120, which includes a waterproof and breathable membrane 122, one side of which is in contact with the outside air, and the other side of which is in contact with the gas inside the high-voltage package 120.
