The metal sheet of the present invention comprises: an attachment sheet attached to a rear cover of the portable terminal; a first metal group which includes a plurality of metal protrusions spaced a set distance apart from each other so as to have a first porosity and is attached to a first region of one side surface of the attachment sheet; a second metal group which includes a plurality of metal protrusions spaced a set distance apart from each other so as to have a second porosity lower than the first porosity and is attached to a second region disposed adjacent to the first region of one side surface of the attachment sheet. According to the present invention, degradation generated in an embedded antenna such as a plat-typed inverted f antenna can be efficiently solved. Also, a receiving sensitivity can be secured by the embedment of an antenna having various receiving bands. Also, a texture can be considerably improved by using the metal protrusions.
