Provided is a method for manufacturing a knob structure which enables light provided from a light emitting device to be recognized as a form of a specific identification symbol, and which comprises: a first step of providing a body portion through which light can be pass and a selective transmitting portion which can be stacked on the body portion and a light transmitting portion allowing the light transmitted through the body portion to be selectively transmitted can be formed in; a second step of stacking the selective transmitting portion on the body portion after processing the light transmitting portion in the selective transmitting portion or processing the selective transmitting portion after stacking the selective transmitting portion on the body portion; a third step of burying a burying agent, through which the light having passed through the body portion can pass, in the light transmitting portion to prevent foreign substances from being introduced into the light transmitting portion; and a fourth step of irradiating an electromagnetic wave from the outside of the body portion so that the burying agent can be hardened by the electromagnetic wave having passed through the body portion. |
