Abstract

The invention aims to provide an electronic device housing that can maintain the antenna performance without deteriorating the radio communication performance, ensures uniform characteristics as one molded electronic device housing in spite of consisting of a plurality of members, and show excellent features in terms of the degree of warpage and dimensional accuracy as well as small deformation in high temperature environments and high mass productivity. The electronic device housing consists mainly of a fiber reinforcing member (a) and a fiber reinforcing member (b), the fiber reinforcing member (a) containing a resin (a1) and a fiber (a2), the fiber reinforcing member (b) containing a resin (b1) and a fiber (b2), the fiber reinforcing member (a) and the fiber reinforcing member (b) being joined directly without the existence of another layer at the joining face between the fiber reinforcing member (a) and the fiber reinforcing member (b), and the fiber reinforcing member (a) and the fiber reinforcing member (b) fulfilling a specific relation in terms of linear expansion coefficient and/or bending elastic modulus.
