Image sensor and electronic camera

An image sensor, comprising

• a first voltage source that supplies a first voltage and
• a plurality of pixels supplied with the first voltage, wherein
• the pixels each include:
• a photoelectric conversion unit that photoelectrically converts incident light;
• an accumulation unit to which an electric charge resulting from photoelectric conversion by the photoelectric conversion unit is transferred and accumulated;
• a transfer unit that transfers the electric charge from the photoelectric conversion unit to the accumulation unit;
• a second voltage source that supplies a second voltage;
• and
• a supply unit that supplies the transfer unit with a transfer signal based on either the first voltage supplied by the first voltage source or the second voltage supplied by the second voltage source;
• and
• the supply unit includes a capacitor arranged between the first voltage source and the transfer unit, and a second resistor arranged between the second voltage source and the transfer unit.
