Abstract:
1. A method for forming a case of an electronic device with a wireless communication function, the case having an antenna region and a non-antenna region, the method comprising: (a) providing a pair of outer prepreg layers adapted to form the antenna region and the non-antenna region, each of the outer prepreg layers containing a fiber that permits permeation of an electromagnetic wave; (b) providing a plurality of inner prepreg layers, each of which includes: a first prepreg sheet that is adapted to form the antenna region and that contains a first fiber, which permits permeation of an electromagnetic wave; and a second prepreg sheet that is connected to the first prepreg sheet and that is adapted to form the non-antenna region, the second prepreg sheet containing a second fiber that prevents permeation of an electromagnetic wave and that has a strength higher than that of the first fiber; (c) stacking and pressing the inner prepreg layers to obtain an inner laminate; (d) disposing the inner laminate between the outer prepreg layers; and (e) forming the outer prepreg layers and the inner laminate in a mold.
