とになるという問題があった。(The problem to be solved by the invention) In the composite optical member as described above, the adhesion strength between the glass base material and the organic polymer layer is increased by subjecting the glass base material to a surface treatment. If left in a high temperature and humid environment for a long period of time (for example, under environmental test conditions, left in an environment with a room temperature of 85°C and a relative humidity of 85% for 500 hours), the adhesion of the interface will decrease, and the organic polymer layer will deteriorate. Peeling may occur from the outer periphery. This tendency is particularly strong when the glass substrate has a composition with low silicon oxide and metal oxide components. Therefore, various treatments must be performed to improve adhesion reliability, but the number of manufacturing steps increases accordingly. There was a problem that this would result in an increase in
