Abstract
A first filler resin is disposed to cover at least an outer peripheral side of a secondary spool and a secondary coil. The second filler resin is filled inside a case and seals a cover sealant which includes a primary coil, secondary spool, a secondary coil, a center core, an outer core and the first filler resin. The connector protrudes to an outside of the case. The case has a fixing portion. The second filler resin has a lower elasticity than the first filler resin. The ignition coil is manufactured by filling the first resin inside the case, and filling the second resin after the first resin is cured.
