I may well be mistaken but that looks like the pad carrier backing plate rather than the pad itself. The pad should look thick and meaty, and yours looks like it's totally worn through!
Hard to be sure from the pictures, but it looks as if the pad has worn down so far the backing plate is almost touching the disc and is about to fall out of the caliper.

Looks that way to me too. Immediate action needed.
