This solid state imaging apparatus is provided within the tip part of an insertable part of an endoscope and is provided with an image forming optical system for forming images. This image forming optical system forms an optical image on the imaging surface of a solid state imaging chip provided in the rear of this image forming optical system. This solid state imaging chip is affixed to a circuit substrate extending substantially at right angles with the imaging surface and electrically connected with the solid state imaging chip. This circuit substrate is connected with a signal cable transmitting input and output signals of the solid state imaging chip.
