A manufacturing method of a solid-state imaging apparatus includes the steps of: preparing a solid-state imaging device having a light receiving region at a main surface thereof; preparing a light transmitting member having an extending portion extending from the solid-state imaging device; preparing a holding member having a space for holding the solid-state imaging device therein, and having a positioning portion for positioning the solid-state imaging device; fixing the light transmitting member to the main surface of the solid-state imaging device in parallel to each other to keep a constant interval therebetween; bringing a side of the solid-state imaging device to meet the positioning portion of the holding member; and fixing the extending portion of the light transmitting member to the holding member.
