Abstract
To reliably drain water to a concave section formed in a case, regardless of the position where fluid drops on an electronic circuit device or the angle of attachment to a vehicle for the electronic circuit device. The electronic circuit device (11) for airbag deployment comprises: the case (12) that opens at a bottom section (12a) and at one side surface (12b); a rear lid that closes the bottom section (12a) of the case (12); a circuit substrate arranged in a range extending from another side surface (12d) to the one side surface side, of a housing chamber formed by the case (12) and the rear lid; and a connector (13) provided in the opened one side surface side. An enlarged diameter section (12c), wherein the opening gradually enlarges towards the outside of the opening end surface, is formed across the entire area in the peripheral direction, excluding the bottom section of the one side surface side of the case (12). Safety is further improved, because the fluid does not come in contact with the connector protruding from the one side surface and cause malfunctions.

However, in order to prevent the liquid dropped on the electronic circuit device 11 from flowing down to the opening end surface of the one side surface 12a, the one side surface toward the outside of the opening end surface is disposed in the entire circumferential direction except for the bottom of the one side surface 12a of the case 12. An enlarged diameter portion 12c in which the opening of 12a gradually expands is formed.
以下、この拡径部１２ｃの具体的な形態を、図２～図４を用いて説明する。
