To be configured inexpensively to enable cost reduction and sense sitting posture of an occupant highly accurately, occupant posture sensing apparatus 100 includes capacitance sensor unit 10 and circuit unit 20. Capacitance sensor unit 10 includes first and second sensing electrodes 11 and 12 provided at portions of vehicle interior ceiling 2 ahead of and right above a seat 40 and connected to capacitance sensing circuit 21 of circuit unit 20 and shield-driving circuit 23 through selector switches SW1 and SW2. CPU 29 of circuit unit 20 determines sitting posture of occupant (human body) 48 sitting on the seat 40 based on information regarding position of head 49 of the occupant 48 by using capacitance values detected by capacitance sensing circuit 21 based on capacitances from sensing electrodes 11 and 12. Posture information regarding the determined sitting posture is output to ECU mounted on a vehicle 1 and used for controlling air bag deployment, etc.
