Lens with infrared ray filter, method of manufacturing the same, and compact camera

A method of manufacturing a lens with an infrared ray filter comprising:

• a molding step for molding a multi-cavity lens molding having a plurality of projections constituting refractive surfaces of the convex surfaces of the convex lenses formed integrally on the surface of the flat plate with glass;
• a film-forming step for providing an infrared ray insulating dielectric multilayer film for cutting the infrared rays on either one of the surfaces of the multi-cavity lens molding;
• and
• a cutting step for cutting the portions of the flat plate of the multi-cavity lens molding provided with the infrared ray insulating dielectric multilayer film into individual projections.

A compact camera comprising:

• a solid-state image sensing device for converting the received light beam into an electric signal;
• a housing covering around the solid-state image sensing device and having an opening;
• and
• a lens with an infrared ray filter provided with an infrared ray insulating dielectric multilayer film for cutting the infrared rays on either one of the surfaces of the glass plane-convex lens including a flat refractive surface on one side and a convex refractive surface on the other side as the entire portion or a part of a lens system for converging the light beam coming through the opening onto the solid-state image sensing device.
