Claim Text:
1. A metal tape material comprising a metal whose crystal structure is face centered cubic lattice structure, wherein an area fraction A wherein an area fraction of a <212> noriented region in which crystal axes <212>of the unit lattice of the face centered cubic structure are within an orientation difference of 15° relative to the thickness direction of the metal tape material and further within an orientation difference of 15° relative to the first in-plane direction of the metal tape material is defined as A wherein the crystal grain size of the crystal grains in an in-plane direction of the metal tape material is 400 μm or greater, wherein the metal is copper, silver, aluminum, or gold, wherein the area fraction A wherein the first direction is the longitudinal direction of the metal tape material.
