摘要： PROBLEM TO BE SOLVED: To provide a highly sensitive imaging device in which a superior imaging signal can be obtained by suppressing occurrence of image failure phenomenon such as a false signal, a ripple phenomenon, and an inversion phenomenon or the like. SOLUTION: On a conductive face 1a of a light-transmissive substrate 1, a light-conductive part 2 is formed. The light-transmissive substrate 1 and a glass tube 4 are sealed by an indium ring 3 in a state that a conductive film 1A and the indium ring 3 are electrically connected so that an internal space of the glass tube 4 is held in vacuum. A shielding ring 10 is pinched by the photo-conductive part 2 and a meshed electrode 9, and a non-forming region in which the light-conductive part 2 is not formed among the conductive film 1A of the light-transmitting substrate 1, and the indium ring 3 are covered by this shielding ring 10. Due to this, the entry of a floating electrons into the conductive film 1A and the indium ring 3 can be suppressed so that the image signal of high quality image can be obtained without accompanying the image failure phenomena such as the false signal, the ripple phenomenon, and the inversion phenomenon or the like.
