Ignition coil for internal combustion engine

An ignition coil for an internal combustion engine comprising:

• a primary coil and a secondary coil which are magnetically coupled with each other;
• a case which includes a case body in which the primary and secondary coils are disposed and a high-voltage tower which is of a hollow cylindrical shape and extends downward from the case body;
• a closing member which is press-fit in the high-voltage tower to close an inside of the high-voltage tower;
• and
• a filled resin which is disposed inside the case body and hermetically seals the primary and secondary coils,
• wherein the closing member includes a resinous cylinder, a high-voltage terminal, and a resistor, the high-voltage terminal being firmly attached to the resinous cylinder and of a hollow cylindrical shape with a bottom and an upper opening facing upward, the resistor being disposed inside the high-voltage tower, and
• wherein the closing member is pressed at an outer peripheral surface of the resinous cylinder against the high-voltage tower.
