Claim Text:
1. A flex-rigid wiring board, comprising: a flexible substrate comprising a base material layer; and a non-flexible substrate comprising an insulating substrate and positioned such that the insulating substrate of the non-flexible substrate is extending in a horizontal direction of the base material layer of the flexible substrate, wherein the flexible substrate and non-flexible substrate comprise a first wiring layer comprising a plurality of non-embedded wirings formed on a first surface of the insulating substrate in the non-flexible substrate and extending on the base material layer of the flexible substrate, and a second wiring layer comprising a plurality of embedded wirings embedded in a second surface of the insulating substrate in the non-flexible substrate and extending on the base material layer of the flexible substrate, the non-flexible substrate comprises a first insulating layer formed on the first surface of the insulating substrate in the non-flexible substrate and having an opening portion exposing at least a portion of the first wiring layer on the base material layer in the flexible substrate, and a second insulating layer formed on the second surface of the insulating substrate in the non-flexible substrate and having an opening portion exposing at least a portion of the second wiring layer on the base material layer in the flexible substrate.
