Imaging apparatus for electronic endoscope and electronic endoscope

An electronic endoscope inserted into a body cavity, comprising:

• an imaging device for imaging an inside of said body cavity,
• wherein said imaging device comprises:
• an objective optical system for taking in an image light of an object in said body cavity;
• an imaging device arranged such that an imaging surface becomes parallel to an optical axis of said objective optical system, said imaging device is constituted of a bear chip, and first signal terminals, said first signal terminals is provided on a surface having said imaging surface, and arranged near the edge portion facing a rear end side of said insertion section;
• a prism for guiding said image light to said imaging surface;
• a cover glass attached onto said imaging surface to form a gap in between;
• a circuit board attached to said bear chip, said circuit board has approximately the same thickness as said bear chip, second signal terminals connected to said first signal terminals by wire bonding are arranged near the edge portion facing a front end side of said insertion section;
• a conducting plate having a width of no less than ¼ width of said bear chip, said conducting plate is arranged along one side of said rear surfaces of said bear chip and said circuit board, and electrically connects said bear chip and said circuit board to each other;
• and
• a forceps channel for inserting a treatment tool into said body cavity, said forceps channel is arranged such that a part of an outer circumference of said forceps channel fits into a cut portion formed on said rear surfaces of said bear chip and said circuit board by said conducting plate.
