Zusammenfassung:	PROBLEM TO BE SOLVED: To mount a pressure sensor on the inner part of the sealed case of an automotive control device without loosing the function of pressure measurement. SOLUTION: An engine control circuit board 15 and the pressure sensor 20 are housed in one control unit case (for example, ECU case) 11. The ECU case 11 (or the cover thereof) comprises a hole 18 for guiding a pressure to be detected. The pressure sensor 20 has a sensor case 22 for housing a gauge chip 21, and installed in the ECU case 11 together with the sensor case 22. The gauge chip 21 is opposed to the hole 18. The sensor case 22 is adhered to the inside of the ECU case 11 or the cover thereof so as to interrupt the hole 18 from the inner part of the ECU case 11. A cover 14 is also adhered to the ECU case.
