Abstract (in Japanese) (See Japanese page) 
(in English) The contact capacitance was investigated by measuring the phase shift between the alternating contact voltage and current of 10 kHz with Cu-Cu and Ni-Ni contacts having a contact resistance of 0.003 to 0.3 Ohm. The contact current flew 7 to 14 degrees (2 to 4 microseconds) in advance of the voltage as if the contact impedance were capacitance-controlled. The resultant capacitances were estimated at 10 to 1000 microfarad in parallel with the tunnel resistances. Also measurements using a capacitance-resistance bridge proved the capacitances to be in agreement with the values mentioned above. Possible theories were proposed.
