PROBLEM TO BE SOLVED: To prevent peeling or decrease in strength in an adhesive R even when optical elements 4, 5 are adhered and fixed apart from a fixing member 3. SOLUTION: A filler comprising spheric particles and a filler comprising pulverized particles are compounded into the adhesive R to be supplied to fill the gap between optical elements 4, 5 and the fixing member 3 so that both fillers are present, fluidity of the adhesive R is increased by the filler comprising spheric particles, a proper viscosity is maintained even when the add amount of the filler is increased, and thereby, the add amount of the filler can be increased. Thereby, while the shape holding property of the adhesive necessary for three-dimensional adhesion of the optical elements 4, 5 is maintained, extremely preferable high transparency, low shrinking property and high temperature stability can be obtained.
