PACS. 74.60Ec - Mixed state, critical field, and surface sheath.
PACS. 74.70Tx - Heavy-fermion superconductors.
PACS. 74.72-h - High-$T_{\rm c}$ compounds.


We re-examine theoretically the upper critical field of UPt3 for both $\vec{H} 
\parallel \vec{c}$ and $\vec{H} \parallel \vec{a}$. We find that the f-wave superconductor(or E2ustate) recently identified can describe the upper critical field determined experimentally consistently, if we assume that the spin component of the order parameter $\vec{d}$ is parallel to the c-axes. The related vortex lattice is also considered.
