A flow measuring device includes a housing including a bypass passage and a flow sensing chip located in the bypass passage and including a sensing surface portion. A throttle portion that is a part of a flowing passage wall facing a sensing surface portion throttles a cross-sectional area of a bypass passage. A position where the throttle portion starts is referred to as a start point position, and a position of the throttle portion where a distance between a gravity center of the sensing surface portion and the throttle portion is shortest is referred to as an end point position. The start point position and the end point position define an imagination line, and the imagination line and the flowing direction define an angle that is in a range from 0 degrees to 20 degrees.

The purpose of the present invention is to provide a motor vehicle internal combustion engine control apparatus which is constructed as a waterproof structure capable of having a long life while minimizing an increase in surface area of a case and a cover, thereby enabling miniaturization, decrease in cost, and increase in reliability to be satisfied. The motor vehicle internal combustion engine control apparatus is equipped with a substrate, a connector, and a case and cover which enclose the substrate, a waterproofing adhesive being disposed at a junction part between the cover and the case. Recessed portions are disposed at the junction part between the case and the cover. The sidewalls of one of the recessed portions are inserted into the other of the recessed portions to form a gap which is folded a plurality of times between the case and the cover and extends between the inside and the outside of the case and cover, said gap being formed so that the size of the gap on the outer side is formed to be larger than the size of the gap on the inner side. The gap is configured to be fluid-tight by the waterproofing adhesive filled in the gap.

The present disclosure provides an electronic device including a casing, a terminal, a substrate, an electric connector, and a conductive adhesive. The terminal is fixed to the casing. The substrate is attached to the casing at a position where at least a portion of the substrate faces the terminal. The electric connector is fixed to a circuit wiring formed in the substrate at a positon where the substrate faces the terminal. The electric connector protrudes toward the terminal from the circuit wiring. The conductive adhesive electrically and mechanically connects the terminal to the electric connector.
