There is provided a high gloss electrodeposited copper foil which can be manufactured in a short time. The electrodeposited copper foil has a fraction of the areas occupied by the {100} plane deviating by 18&#xb0; or less from the &#x3c;001&#x3e; crystal orientation of 10% or more determined by analysis of the surface by electron backscatter diffraction (EBSD) and at least one surface of the electrodeposited copper foil has a glossiness G(20&#xb0;) of 1,500 or more, determined in accordance with JIS Z 8741-1997.

Electrolytic copper foil and manufacturing method therefor

A composite metal foil is provided comprising a porous metal foil comprising a two-dimensional network structure composed of a metal fiber, and a primer provided on at least a part of the interior and/or periphery of pores of the porous metal foil. According to the present invention, it is possible to obtain a composite metal foil which has a desired function imparted by a primer in addition to superior properties derived from a porous metal foil, in a highly productive and cost effective manner that is suited for continuous production.

Composite metal foil and production method therefor

A reinforced porous metal foil is provided including a porous portion comprising a two-dimensional network structure composed of a metal fiber and a reinforced portion which is substantially non-porous or less porous than the porous portion. The reinforced portion is composed of the same metal the metal fiber and is continuous and integral with the porous portion. Accordingly, it possible to provide a porous metal foil having superior properties at a low cost in a highly productive manner that is also suitable for continuous production.

Reinforced porous metal foil and process for production thereof

The porous metal foil of the present invention include a two-dimensional network structure composed of a metal fiber. This porous metal foil has a first side having a higher glossiness, and a second side having a lower glossiness located on the opposite side of the first side. The ratio of glossiness Gof the first side to glossiness Gof the second side, G/G, as measured at incident and reflection angles of 60 degrees in accordance with JIS Z 8741 (1997) is from 1 to 15. The present invention provides a highly useful porous metal foil which has a reduced difference in properties between both sides, in addition to the superior properties attributable to a porous metal foil, in a highly productive and cost effective manner that is suited for continuous production.

Porous metal foil and production method therefor

A porous metal foil of the present invention comprises a two-dimensional network structure composed of metal fibers. This porous metal foil has superior properties and can be obtained in a highly productive and cost effective manner.
