Image pickup module

Abstract

An image pickup module is provided with: an electric cable (1); a solid-state image pickup element (22) having an image pickup section (21) orthogonal to the axis line direction of the leading end of the electric cable (1); and a flexible wiring board (30, 30A), which has an element mounting section (32) having the solid-state image pickup element (22) mounted thereon, two extending sections (34e, 35e) that are bent on both the sides of the element mounting section (32) and extending from the element mounting section (32) such that the extending sections are closer to each other when further from the element mounting section (32), two connecting piece sections (34f, 35f) extending in the axis line direction of the leading end of the electric cable (1) from the two extending sections (34e, 35e), said two connecting piece sections being on the side opposite to the element mounting section (32), and terminal sections (34c, 34d, 35c, 35d) that are connected to the electric cable (1) by being provided on the two connecting piece sections (34f, 35f), said flexible wiring board electrically connecting between the solid-state image pickup element (22), and the electric cable (1).

Description

technical field [0001] The present invention relates to an imaging module having a structure in which a solid-state imaging element and a cable are electrically connected via a flexible wiring board, a camera module with a lens configured using the imaging module, an endoscope, a method for manufacturing the imaging module, and a flexible wiring board molding device. [0002] This application claims priority based on Japanese application No. 2012-082972 for which it applied on March 30, 2012, and uses the content here. Background technique [0003] Conventional electronic endoscopes often have a configuration in which an imaging module including an imaging unit having a solid-state imaging element (hereinafter, simply referred to as imaging element) is housed in an insertion portion of the electronic endoscope is assembled at the tip of a cable. [0004] The imaging unit as the imaging module widely adopts a configuration in which a flexible printed circuit board (hereinafte...

Problems solved by technology

[0008] However, since this configuration requires a block processed with high precision, and the FPC must be correctly fixed to the block, assembly is troublesome.

In addition, in the structure where the conductor of the cable is soldered to the parts arranged on both sides via the FPC block, the size including the soldered part and the conductor coating cannot be easily reduced, which is not conducive to the reduction of the diameter of the imaging unit (reduction Smaller diameter of the imaging unit) and downscaling of the tube of the endoscope (reducing the diameter of the endoscope)
