Abstract
An integrated ignition apparatus has a coil section and a plug section. The coil section has a spring as a connection member internally. The spring electrically connects other inside terminal members of the plug section. When the coil section and the plug section are integrated, the spring is pressed, and resiliently deforms in the axial direction. Spring-back force of the spring maintains electrical connection steadily, and prevents disconnection of the spring and the terminal members due to vibration. This structure prevents failure in electric conduction between the coil section and the plug section.
