PURPOSE:To decrease the number of parts, by molding a case, which encloses a pipe part wherein intake air flows and a substrate for electronic circuits; and connectors, which connect a power source for the circuits, output signals, and the like to the outside; as a unitary body by synthetic resin. CONSTITUTION:A substrate 6 for electronic circuits is enclosed in a case 4a. A terminal 8b and a conducting piece 10a, which are embedded when the case 4a is molded by synthetic resin, are soldered to the required part of the substrate 6. The side of the opening part of the case 4a, into which the substrate 6 for the electronic circuits is incorporated in this way, is bonded and fixed to the surface of one side of a pipe 1a so that the inner part is tightly sealed. |
