An electronic control device has an enclosure accommodating therein a circuit board and having (a) a first enclosure member which is provided at a connecting part thereof with a seal groove and (b) a second enclosure member which is provided at a connecting part thereof with a convex line that is fitted into the seal groove of the first enclosure member; a protrusion formed on either one of an inner wall surface in the seal groove or an opposing surface, which faces the inner wall surface of the seal groove, of the convex line so as to protrude toward the other surface. The protrusion limits a movement, in a seal groove width direction, of the convex line fitted into the seal groove. The seal groove and the convex line are sealed with a sealant. |
