Abstract
A solid state image pick-up device has shields for suppressing deterioration in a ratio of an output signal to output noises caused by crosstalks, suppressing deterioration in a ratio of the output signal to output noises caused by a coupling capacity, and suppressing deterioration in a ratio of the output signal to output noises caused by imbalance is provided. Shielding lines 301, 302, and 303 are arranged in a layer to which output lines 210 and 220 belong. Shielding lines 304, 305, and 306 are arranged over the shielding lines 301, 302, and 303, respectively. Further, shielding pins 307, 308, and 309 are arranged between the shielding lines 301 and 304, between the shielding lines 302 and 305, and between the shielding lines 303 and 306, respectively. No shielding line is arranged over output lines 210 and 220. A structure is made to be plane-symmetrical with respect to a plane including a center line of the shielding line 301 and a plane including a center line of the shielding line 304.
