<p>A solid-state image pickup device (1) of the present invention is provided with: an image pickup region (101) wherein pixels (100) that photoelectrically convert inputted light into pixel signals are disposed in matrix; vertical signal lines (108), which are respectively disposed for pixel rows, and which read out the pixel signals; and a current source (105) connected to the vertical signal lines (108). The current source (105) is provided with: three transistors (M2y, M3y, M4y (1≤y≤j)), which are disposed between the vertical signal lines (108) and a GND line, and which are connected in series; and a transistor (M5y) having the drain and the source thereof connected to two connecting points where the adjacent transistors (M2y, M3y, M4y) are connected to each other.</p> |
