Summary:Provided are an endoscope and an endoscope system, wherein a high voltage is prevented from being applied to an image pickup element at the time when a pulse signal is stopped and at the time of start up. An endoscope 2 is provided with: a first chip 21 having a first buffer 26 that outputs image pickup signals to the outside, said image pickup signals having been generated by means of a light receiving unit 23; and a second chip 22 having a second buffer 27, which amplifies the image pickup signals outputted from the first buffer 26, and outputs the signals to a transmission cable 3. The first buffer 26 applies a predetermined voltage to the second buffer 27 during a period when the light receiving unit 23 is not outputting the image pickup signals, thereby outputting a direct current power at a predetermined level to the transmission cable 3 from the second buffer 27. 提供如下的内窥镜和内窥镜系统：能够防止在脉冲信号停止时或启动时对摄像元件施加较高的电压。内窥镜(2)具有：第芯片(21)，其具有第缓冲器(26)，该第缓冲器(26)将受光部(23)所生成的摄像信号向外部输出；以及第二芯片(22)，其具有第二缓冲器(27)，该第二缓冲器(27)对从第
