A solid-state imaging device includes an imaging region in which unit pixels which are obtained by arranging color filters in a photodiode are two-dimensionally arranged in matrix, and readout signal lines which are provided in plural with respect to an arbitrary one row at which the plurality of unit pixels are arranged, in which the readout signal lines are provided according to the number of color types of the plurality of unit pixels which are arranged at the one arbitrary row, and the same readout signal lines are connected to unit pixels of which color of color filters are the same, in the plurality of unit pixels which are arranged on the one arbitrary row.
