A composite optical device comprises an optical element bonded onto a support body with an adhesive, at least a part of surfaces of the optical element being covered by a film made of a hydrophilic material. A method for manufacturing a composite optical device having an optical element bonded onto a support body with an adhesive, comprises the steps of: preparing a bar-shaped optical element having a length not less than twice the width thereof and having surfaces at least a part of which is covered by a film made of a hydrophilic material, and bonding the bar-shaped optical element on the support body with the adhesive; and cutting the bar-shaped optical element, the adhesive and the support body while applying a liquid containing water at least to portions where they are cut.
