TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The anchoring layer is: formed on at least part of the light incident side or the main side opposite to the light incident side; and formed in the form of a rib, or the anchoring layers are formed in the form of columns. The anchoring layer contains at least one adhesive comprising thermoplastic, thermosetting, room-temperature-setting or energy ray-setting adhesives. The energy ray-setting adhesive is an UV-setting adhesive. The covering section is: formed to have a height extending from the surface of the anchoring layer to the light incident side; and formed to have a height extending from the main side of the first and second base materials opposed to one of the main sides to the light incident side. The covering section includes at least one of silicone-based resin, modified silicone-based resin, urethane-based resin, polysulfide-based resin, modified polysulfide-based resin, telechelic polyacrylate-based resin, acrylic resin, acrylic urethane-based resin, vinyl acetate-based resin, acrylonitrile, hydrocarbon resin, alkylphenol resin, rosin-based resin, polyvinyl ether, synthetic rubber or natural rubber. The module further comprises: a hollow layer between the light incident side and one of the first and second base materials; a hollow layer between the main side opposite to the light incident side and one of the first and second base materials; a sealant provided between the peripheral portions of the first and second base materials; and a shielding material provided between the peripheral portions of the first and second base materials. The light incident side is in close contact with one of the first and second base materials. The photoelectric conversion element includes a transparent base material, an opposed base material, and a power generating element section, where the sealing portion is provided between the peripheral portions of the transparent and opposed base materials. The photoelectric conversion element has a lateral side provided between the peripheral portions of the light incident side and the main side opposite to the light incident side, where the sealing portion is provided on the peripheral portion of the light incident side, that of the main side opposite to the light incident side or the lateral side. The first base material is a first glass plate, and the second base material is a second glass plate.
