Abrégé

A spark plug (1) for internal combustion engines has a centre electrode (6) arranged along a central axis (2) of the spark plug (1), which electrode is enclosed by an insulator (5) at least in portions, and a housing (9) in which the insulator (5) is received, at least in portions. A gap (20) is formed, at least in portions, between the insulator (5) and the housing (9). The gap (20) is at least partially filled with a material (23) having a thermal conductivity (λ) ≥ 1 W/(m*K).
