An air heater for internal-combustion engines is provided to easily perform an installation and a ground to a chassis of the air heater by excluding an interface between a conventional minus terminal and a throttle actuator. In an air heater for internal-combustion engines, a heater element is installed on a central penetration part of a heater housing(20). A plus terminal and a minus terminal are exposed to the outside by penetrating a circumference of the heater housing. A throttle body(30) and an intake manifold(50) are placed on a top surface and a bottom surface of the heater housing. The plus terminal and the heater housing are insulated. The minus terminal and the heater housing are conducted. And, a conducting member(60) is conducted by connecting a predetermined portion of the heater housing to the intake manifold.
