Your keyboard is a collection of switches in a grid pattern (X & Y). So what can happen is either pressure from a blistered battery is pushing on them or you had a liquid spill which damaged the contacts. What you are seeing is the horizontal line servicing the X, C, V, B & N letters ', . keys and two of the arrow keys is bad.
As this is also the row thats closest to the battery I'm hoping the battery is the issue. Here is the IFIXIT guide you'll need to follow: MacBook Pro 13" Unibody Mid 2012のバッテリーの交換 and depending where you live here is the IFIXIT battery with the needed tools and sundries: MacBook Pro 13" Unibody (Mid 2009-Mid 2012) Battery You can also get the battery alone MacBook Pro 13" Unibody (Mid 2009-Mid 2012) Battery if you already have the needed tools.
If you did spill something into the keyboard then thats were you'll need to replace the keyboard which would require you replace the uppercase assembly MacBook Pro 13" Unibody Mid 2012 Upper Case Replacement and here's the uppercase part: MacBook Pro 13" Unibody (Early 2011-Mid 2012) Upper Case

thanks for answering,I just want to correct my self first that my laptop is
MacBook Pro 13" Unibody Mid 2012
not MacBook Pro 13" Retina (Late 2012/Early 2013)
so dose that make any difference about the problem??
and actually I don't know what happend to keyboard before as I buy it with this problem and the seller blocked me
Yes the corrected model info does change things a bit. I've gone back and corrected my answer so now the proper guides and parts are listed.
But without knowing the batteries status I can't get you more focused here on what is needed. Did you download CoconutBattery and run it? If you ave how about posting a screenshot of the main window of the app so we can see.
I have just added a picture of the main window of the app,what do you think about the battery,is it in good status?thanks again!
Well, your battery looks OK from the cycle count but the temp look high running off battery. You'll need to inspect it to be sure. Pop the bottom cover and take the battery out its quite easy in this model place it on a flat surface does it rock? If it does its time for a new battery.
Otherwise you have a bad keyboard or both!
