Summary
Description 
This symbol is used for:
 the set of all integers.
 the group of integers under addition.
 the ring of integers.
It comes from LaTeX, I created it in the following way. First I compiled this LaTeX code into PDF using pdflatex: \documentclass{article}
\usepackage{amssymb}
\begin{document}
\begin{equation}
\mathbb{Z}
\end{equation}
\end{document}
Then I opened the PDF document with GIMP, converted to PNG and cropped the part containing the Z. Finally I opened the PNG file with Inkscape and I have traced the bitmap to SVG.
