PROBLEM TO BE SOLVED: To provide an energy ray detector for inhibiting the decrease in the amount of saturation electric charge and an opening ratio. SOLUTION: Since a vertical charge transfer channel 2v transfers an electric charge in a vertical direction, a sensitive region at a second position X2 is positioned on the extension line of a dead region even if a first surplus electric charge discharge region 31, namely the dead region, is provided at a first position X1 for inhibiting the blooming phenomenon. Even if a second surplus electric charge discharge region 32 is provided at a second position X2, the dead region at the first region X2 is positioned on the extension line. When the amount of electric charges at the first and second positions X1 and X2 is added, an electric charge to be generated at a position in a width direction corresponding to one dead region can be complemented by the other. More specifically, when an image pickup in a width direction is to be made, the decrease in the amount of saturation electric charge and the opening ratio can be inhibited.
