Abstract

A wiring substrate comprises: a flexible substrate having a first region and a second region; a wiring line formed on the flexible substrate; and an electronic element that is disposed on the flexible substrate in the first region and electrically coupled to the wiring line. Flexibility of the first region is lower than flexibility of the second region.

Claims (18)

1. A method for manufacturing a wiring substrate, comprising:

forming a wiring line on a flexible substrate having a first region and a second region;

reducing flexibility of the first region of the flexible substrate; and

fixing an electronic element to the first region,

wherein the flexible substrate includes a resin to be hardened by applying predetermined energy, and the energy is supplied to the first region in the reducing of the flexibility of the first region.

2. A method for manufacturing a wiring substrate, comprising:

reducing flexibility of a first region of a flexible substrate;

forming a wiring line on the flexible substrate; and

fixing an electronic element to the first region,

wherein the flexible substrate includes a resin to be hardened by applying predetermined energy, and the energy is supplied to the first region in the reducing of the flexibility of the first region.

3. The method for manufacturing a wiring substrate according to claim 2 , wherein the reducing of the flexibility of the first region further includes forming a reinforcing layer having flexibility lower than flexibility of the second region.

4. The method for manufacturing a wiring substrate according to claim 2 , wherein the flexibility of the first region is continuously reduced in a peripheral region thereof in the reducing of the flexibility of the first region.

5. The method for manufacturing a wiring substrate according to claim 2 , wherein the electronic element further includes a terminal, and the terminal is electrically coupled to the wiring line to fix the electronic element on the flexible substrate in the fixing of the electronic element.

6. A method for manufacturing a wiring substrate, comprising:

forming a wiring line on a flexible substrate;

fixing an electronic element to a first region of the flexible substrate; and

reducing flexibility of the first region,

wherein the flexible substrate includes a resin to be hardened by applying predetermined energy, and the energy is supplied to the first region in the reducing of the flexibility of the first region.
