This document is an executive summary of the German Roadmap on Astroparticle Physics from 2010. It has been revisited with respect to the actual status of the field. We focus on those questions which are of relevance to particle physics rather than to astrophysics. The document is submitted by the Komitee für Astroteilchenphysik (KAT, Committee for Astroparticle Physics) which is the elected representation of all German astroparticle physicists at Universities, Helmholtz Centers and Max-Planck Institutes (about 600 FTE). Our description and recommendations are in accordance with the ASPERA Roadmap for Astroparticle Physics and the ASPERA Input to the European Strategy Process; at the same time we highlight the German priorities.
