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 high-voltage terminal which is press-fit in the high-voltage tower to close an inside of the high-voltage tower, the high-voltage terminal being of a hollow cylindrical shape with a bottom and an upper opening facing upward;
• a resistor which is fit in the high-voltage terminal;
• and
• a filled resin which is disposed inside the case body and hermetically seals the primary and secondary coils,
• wherein the high-voltage terminal includes a pressed wall and a non-pressed wall which are arranged adjacent each other in a vertical direction, the pressed wall being pressed against the high-voltage tower, the non-pressed wall being not pressed against the high-voltage tower, and
• wherein the resistor is fit in the non-pressed wall.
