As parts like that typically live inside devices, getting them can be a bit tricky. You typically need to contact the manufacturer of the device. Does Denso build those units? If so, you can try your luck and see if they might be able to help, but I wouldn't imagine it being easy. Alternatively, those cables are known as 'Flixible Flat Cables' and if you can count the conductors (it looks like 14 to me, but you need to confirm that) and can measure the spacing, then you may be able to source it externally. They may not be the exact length, but you can probably work around that. Examples of such: http://www.ebay.com/itm/PRINTER-AWM-20798-Flexible-Flat-Cable-14Pin-L10in-W15mm-/230294102567
