Abstract
The present invention provides: a highly transparent optical member which is formed from a silicone resin or a silicone rubber, and which has less mass change and excellent heat resistance without causing contact faults, or deterioration or contamination of the surface of other members due to adhesion to an electronic circuit or the surfaces of other members; and a production method for producing said optical member. According to the production method, the content of low-molecular-weight siloxanes D-Din a optical member is reduced to an infinitesimal amount with use of a plurality of different low-molecular-weight siloxane removal steps.
