Did the Concorde have flat plate airfoil? enter image description here

this is because in all the images I have found it appears to be a flat plate enter image description here

  • $\begingroup$ Simple images like that are not what you should be using to base an assumption off, but even in those images you can see it is not a flat plate. $\endgroup$

The Concorde, like many other supersonic aircrafts, had very thin airfoil mainly due to aerodynamic reasons. This answer gives a good overview on this topic.

Anyway the airfoil was definitely not flat i.e. neither a straight line nor without thickness. The following picture shows the central section of a Concorde and it can be seen that the airfoil there was quite thick:

Following one rib from the leading edge to the trailing edge, like the 33+51 in the next cutaway (source), one can more or less unterstand the airfoil shape:

Some reasons for the wing having a delta shape and not being flat can be found in this answer.
