<p>A noncontact transformer installed on the floor of a housing whereby air entrapment within the resin that fills spaces in the transformer is prevented. A primary transformer component is provided on a lower surface of a primary housing, which is then filled with resin. Primary transformer component includes a core space which is defined by inclined internal wall that extends away from the lower surface to form a widely open end of the core space that is larger than the end at the lower surface. <IMAGE></p>
