There is proposed an engine controller which is excellent in reliability in that the outer peripheral edge face (cut surface) of covering member can be prevented from being rusted while securing the water-proofness and dust-proofness. This engine controller comprises a circuit board (12) for controlling an engine; an aluminum die-cast main case body (20) having an open top; and a covering member (30) made of an iron-based metal plate which is preliminarily applied with surface treatment, the covering member (30) being fixedly clamped to the main case body (20) by means of a setscrew (40) so as to hermetically close the open top of the main case body (20); wherein the main case body (20) is provided thereon with a pedestal (24) or groove (25) on which a liquid or jellied water-proofing adhesive (50) is coated or filled (piled), thereby enabling entire outer peripheral edge face (33a) of the covering member (30) to be covered by the water-proofing adhesive (50).
