Abstract
A manufacturing method for a liquid lens device includes: preparing a body having a liquid chamber, a conductive first liquid stored in the liquid chamber, an insulating second liquid stored in the liquid chamber, an electrode kept in contact with the first liquid, and a liquid discharge passage for making the communication between the inside and the outside of the liquid chamber; applying pressure to the first and second transparent substrates to thereby compress the sealing member and discharge the first liquid through the liquid discharge passage to the outside of the liquid chamber; and closing the liquid discharge passage.
