Whether a human body is touching or not is detected highly accurately at high speed. Switch SW1 is turned on to charge condenser Ca by power supply Vcc. The switch SW1 is turned off to transfer the electric charge charged in the condenser Ca to condensers Cs and Cx. The switches SW2 and SW3 are repeatedly turned on and off for a predetermined short time, and thus the electric charge charged in the condenser Ca is slowly discharged through resistor R. The unknown charging voltage Vx of the condenser Cx is compared with the reference voltage Vref by comparator Comp, and the unknown capacitance of the condenser Cx is computed based on the number of times to count turning on and off until it is smaller than the reference voltage Vref. When the computed unknown capacitance of the condenser Cx is the value near the capacitance of a human body, it is determined that a human body is touching. The invention can be applied to a touch sensor.

To obtain an air conditioning apparatus which provides a favorable atmosphere to the ear and saves energy even if the suction resistance of the impeller becomes high due to such as dust in the air conditioning apparatus. The air conditioning apparatus is provided with an impeller which is formed by a plurality of vanes and a ring for supporting the plurality of vanes, and includes a nozzle portion formed by a stabilizer and an air outlet, a cross flow fan formed by a guide wall, and a heat exchanger. The ratio H/&phgr;D2 of the outside diameter &phgr; D2 of the impeller to the height H of the air conditioning apparatus is 2.2 or above and 3.0 or below.
