IMAGE PICKUP UNIT AND ELECTRONIC ENDOSCOPE INCLUDING THE IMAGE PICKUP UNIT

摘要

An image pickup unit includes: a circuit substrate electrically connected with an image pickup device that detects an image of an object, the circuit substrate including a land at least on a surface thereof; a connecting member having conductivity and fixed to the circuit substrate; a wiring connecting portion provided on the connecting member; a substrate connecting portion extended bent from a side portion of the wiring connecting portion, and electrically connected to a land; and a wiring configured to be connected to the wiring connecting portion and electrically connected to the land through the connecting member.

主权项

1. An image pickup unit comprising:
an image pickup device; a circuit substrate electrically connected with the image pickup device; a connecting member having conductivity and fixed to the circuit substrate; and a cable connected to the circuit substrate and the connecting member, wherein the circuit substrate includes:
a bonding substrate portion electrically connected to a rear surface of the image pickup device and having an area substantially same as an area of the rear surface of the image pickup device;a laminated substrate portion extended rearward from a substantially center of the bonding substrate portion;a land for signal line arranged on at least a surface of the laminated substrate portion; anda land for ground arranged on at least the surface of the laminated substrate portion, wherein the connecting member includes:
a wiring connecting portion provided superimposed on a proximal end surface of the laminated substrate portion in parallel with the proximal end surface; anda substrate connecting portion extended bent from a side portion of the wiring connecting portion, and electrically connected to the land for ground, and wherein the cable includes:
a signal line configured to be connected to the land for signal line; anda shield bundle formed by bundling a ground line of the cable with a shield of the signal line, a distal end of the shield bundle being electrically connected to a plane of the wiring connecting portion which is superimposed on the proximal end surface.
