A joined optical memberincludes: a hardly adhesive lens Lthat is formed of a hardly adhesive material; an easily adhesive lens Lthat is formed of a easily adhesive material and is provided parallel to the hardly adhesive lens Lin an optical axis direction; a bonding member that includes an exposed portionand is embedded in the hardly adhesive lens L, the exposed portionbeing exposed to an outer peripheral portionof a facing surface Lof the hardly adhesive lens Lthat faces the easily adhesive lens L; and an adhesivethat allows the easily adhesive lens Land the exposed portionof the bonding memberto adhere to each other. The easily adhesive material has higher adhesiveness with the adhesive than the hardly adhesive material.

Joined optical member

An optical lens, which has a lens section with a refractive power, has concave marks, andwhich are formed to be recessed on a surface of the lens section, in an effective optical lens surface which contributes to image forming of the lens section. A width of each of these concave marks, andis equal to or greater than 0.05 &#x3bc;m and equal to or less than 14 &#x3bc;m, and a depth of recession of each concave mark is equal to or greater than 0.05 &#x3bc;m and equal to or less than 5 &#x3bc;m.

It is proposed an optical substrate of which at least one surface is combined with an optical member made of a material that is different from that of the optical substrate, so as to form an optical element, in which an edge face is formed on at least a portion of an outer circumferential face of the optical substrate, and the edge face is formed in a tapered shape that is centripetally reduced from a side of the surface combined with the optical member towards an opposite side thereof.
