PURPOSE: An injector sealing structure of a diesel engine is provided to prevent failure of engine by improving oil and gas sealing performance, while simplifying configuration by reducing parts count. CONSTITUTION: A gasket(50) is inserted into an insertion hole(21) formed at a cylinder head(20), and an injector(10) is inserted into the gasket. The gap formed between the injector and the cylinder head is sealed by the gasket. The gasket includes a horizontal portion(51) having a hole for penetration of a nozzle(11) of the injector; and a vertical portion(52) formed at the outline of the horizontal portion. The horizontal portion seals the gap formed between the injector and the bottom surface of the insertion hole of the cylinder head. The vertical portion seals the gap formed between the injector and the vertical surface of the insertion hole of the cylinder head.
