Abstract: An endoscope configured to operate with a power supply voltage supplied from a processing device connected to the endoscope through a transmission cable is provided. The endoscope includes: a first chip including: an imaging element; and a first buffer configured to externally output an imaging signal generated by the imaging element; and a second chip including a second buffer configured to amplify the imaging signal output from the first buffer and output the amplified imaging signal to the transmission cable. The first buffer is configured to apply a predetermined voltage to the second buffer in a period in which the imaging element does not output the imaging signal to cause the second buffer to output a direct current at a predetermined level to the transmission cable.
