Title:
MEMBER FOR OPERATION SWITCH, KEY PANEL, ELECTRONIC APPARATUS, AND METHOD FOR MANUFACTURING MEMBER FOR OPERATION SWITCH
Document Type and Number:
Japanese Patent JP2013030281
Kind Code:
A
Abstract:

To provide a member for an operation switch having a concealing layer capable of sufficiently permeating laser light, and a light shielding layer capable of restraining a by-product.

A member of an operation switch has a concealing layer 30, and a light shielding layer 40. The concealing layer 30 is formed of a material with permeability for permeating laser light of a predetermined wavelength, and deteriorates visibility when the light shielding layer 40 is seen from a surface side of the concealing layer 30 in comparison with the transparent material. The light shielding layer 40 is formed of a material for further improving light permeability than that before radiation when the laser light is radiated from the surface side of the concealing layer 30, and for further restraining at least one of gas and soot than when at least one of carbon and iron oxide is contained as a material. A laser light radiation portion of the light shielding layer 40 is modified by radiating the laser light from the surface side of the concealing layer 30. By this modification, a display part 42 for further improving light permeability in a visible light region than at other portions of the light shielding layer 40 is formed.
