Abstract:
1. A physical quantity sensor comprising: a first member; a second member; a sensing member interposed in contact between said first and said second members, said sensing member being configured to generate an electrical signal as a function of a physical quantity applied thereto through one of said first and said second members; a temperature detector detecting a temperature of said sensing member; a correcting circuit correcting the electrical signal generated by said sensing member using the temperature detected by said temperature detector and outputting the corrected electrical signal; and a heat conduction path thermally connecting said sensing member and said temperature detector, said heat conduction path being formed through said second member such that said second member has a thermal resistance along said thermal conduction path which is less than a thermal resistance of said first member in an application direction of the physical quantity, wherein said second member is made of a material having a thermal conductivity higher than that of a material of which said first member is made.
