    • PROBLEM TO BE SOLVED: To provide a physical quantity sensor capable of reducing stress applied from a pad part to a sensing part.SOLUTION: On one face of a substrate 34, relaxation parts 46 are arranged adjacent to a pad part 45. The thermal expansion coefficient of the relaxation part is made smaller than that of the substrate when that of the pad part 45 is greater than that of the substrate 34. The thermal expansion coefficient of the relaxation part is made greater than that of the substrate 34 when that of the pad part 45 is smaller than that of the substrate. As a result, when stress is applied by the pad part 45 to the substrate 34, since stress oppositely-oriented to the above stress is applied by the relaxation parts 46 to the substrate 34, the stress applied by the pad part 45 to the substrate 34 can be relaxed. Therefore, it is possible to suppress stress to be applied by the pad part 45 to a sensing part 36.

    • PROBLEM TO BE SOLVED: To satisfactorily connect a sensor chip and a circuit board via an adhesive.SOLUTION: A pad opening part 20a for exposing a circuit pad 11 is formed in a protective film 20. Also, an adhesive opening part 20b for exposing a prescribed area of a circuit board 10 is formed in the protective film 20. A sensor chip 30 is joined to an adhesive 40 arranged in the adhesive opening part 20b. Consequently, a level difference between the circuit board 10 and protective film 20, in other words, the end part of the adhesive opening 20b restrict spread of the adhesive 40 in the planar direction of the circuit board 10. Accordingly, covering of the circuit pad 11 with the adhesive 40 can be restricted. Additionally, the protective film 20 restricts spread of the adhesive 40 in the planar direction of the circuit board 10. Accordingly, the need to form a specific shape on the circuit board 10 is eliminated, and also a wiring pattern formed on the circuit board 10 is not limited in particular.
