Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inexpensive package for optical communication which can maintain superior airtightness even when its size becomes smaller and the area of the junction interface between an optical window material and a metallic frame member becomes narrower. SOLUTION: One surface 11a of the optical window material 11 is bonded to the corresponding surface of the metallic frame member 17 with glass 14 having a low melting point. The glass 14 is applied not only to the surface 11a, but also to the side face 11b or top face of the material 11 successively provided from the surface 11a. When the metallic frame member 17 has a projecting edge section 17b nearly perpendicularly protruded from the outer periphery of a plate frame section 17a, the window member 11 is bonded to the frame section 17a and edge section 17b with the glass 14.
