Yes, looks just like an ebony board. You can normally tell it from rosewood by the fact that the board is very smooth, whilst rosewood has more pores and a more open grain. Most of the ebony from a tree is not in fact black, but is like your fretboard. A lot of ebony was wasted because people only wanted the black wood from the tree, and a lot of the rest was historically thrown away (adding to the general shortage of ebony in most locations). Now ebony is scarcer and only really obtainable form a very few countries, people are rightly making far more use of the non-black ebony. It's still a great fingerboard material. I had a Warmoth parts Tele that had an ebony neck like yours.
