A temperature compensation circuit having satisfactory linearity, a trimming circuit including a plurality of temperature gradients, and an acceleration detector having a wide applicable temperature range. A plurality of resistor elements R1 to R4, R5 to R8, R21 to R24, R25 to R28 are connected in series between a power supply voltage line and a ground voltage line. Resistor elements R9 to R14 are connected in series between connection nodes N1 and N3. Resistor elements R29 to R34 are connected in series between connection nodes N2 and N4. The resistor elements R1, R2, R4, R5, R7 to R14, R24, R25 have negative temperature coefficients. The resistor elements R3, R6, R21 to R23, R26 to R34 have positive temperature coefficients. An output terminal NT5 connects a connection node of the resistor elements R13 and R14 and a connection node of the resistor elements R30 and R29.
