Patent ID: 11799199

Abstract:
The present invention aims to provide an electronic device housing that is able to maintain the antenna performance without deteriorating the radio communication performance, excellent in terms of the degree of warpage and dimensional accuracy, and mass productivity. The electronic device housing includes a fiber reinforcing member (a) and a fiber reinforcing member (b), wherein the fiber reinforcing member (a) contains a resin (a1) and a fiber (a2), the fiber (a2) being in the form of discontinuous fibers; the fiber reinforcing member (b) contains a resin (b1) and a fiber (b2), the fiber (b2) being in the form of continuous fibers; the projected area of the fiber reinforcing member (a) accounts for 60% or more of the total projected area, which accounts for 100%, of the housing projected onto the plane of the top face; and requirements (i) and/or (ii) given below are met: (i) the resin (a1) is a thermoplastic resin having a melting point of more than 265° C., and (ii) the resin (a1) is a thermoplastic resin having a water absorption rate of 0.4% or less.
