Document Type and Number:
WIPO Patent Application WO/2011/081148
Kind Code:
A1
Abstract:
Disclosed is a key-top structure, an electronic device, and a method of manufacturing the key-top structure, wherein a clicking feeling upon pushing-in the key-top structure is excellent, or wherein deformation of a key-top member that takes place when manufacturing the key-top member by hardening ultraviolet-curing resin can be alleviated. The key-top structure (60) is provided with: the key-top member (61), wherein a sheet-formed section (61b) and a plurality of key-tops (61a) are formed by hardening ultraviolet curing resin, the key-tops (61a) are made to have a greater thickness dimension (T) than the sheet-formed section (61b), and a section exists therein where the plurality of key-tops (61a) are arranged in row-form with a prescribed gap given therebetween; and a deformation alleviating means for alleviating deformation due to contraction of the key-top member (61) after the hardening thereof, when forming the key-top member (61) by hardening ultraviolet curing resin onto a base material.
