Abstract

A multipoint ignition device for igniting an air-fuel mixture in a combustion chamber of an engine includes: an insulating member formed in an annular shape such that an inner periphery thereof faces the combustion chamber; a plurality of electrodes held on the insulating member so as to form a plurality of ignition gaps inside the combustion chamber; a main body portion provided on an outer periphery of the insulating member; and an intermediate member that is provided between the main body portion and the insulating member and has a larger thermal expansion coefficient than the insulating member.
