The invention provides a rigid-flex board and a mobile terminal. The rigid-flex board comprises a flexible base material layer, a
copper foil layer, a hard layer, a solder-resistant ink layer and a circuit layer, wherein the
copper foil layer is laminated on the flexible base material layer; the hard layer is arranged on one side, away from the flexible base material layer, of the
copper foil layer; the solder-resistant ink layer is arranged on the hard layer, a hollow window is formed in the solder-resistant ink layer for exposing a part of the hard layer, and the hollow window divides the solder-resistant ink layer into two parts facing each other, clamping grooves are formed in the two parts, and the two clamping grooves are communicated with the hollow window, the circuit layer is arranged in the hollow window and laminated on the hard layer, and both ends of the circuit layer are clamped in the two clamping grooves separately. According to the rigid-flex board and the mobile terminal provided by the invention, the two clamping grooves of the solder-resistant ink layer are used for clamping both ends of the circuit layer, so that the solder-resistant ink layer has a compression acting force on the circuit layer, the circuit layer can be prevented from being separated from the hard layer due to pulling situation when the circuit layer is connected with an electronic element, the connection strength between the circuit layer and the hard layer is enhanced, and the conduction connection of the circuit layer and the electronic element is ensured.
