PROBLEM TO BE SOLVED: To simultaneously attain the prevention of moire and the prevention of lightness/darkness unevenness by preventing moire created when the mesh pattern of the conductor layer provided in a glass pane and a glass door for use such as crime prevention is overlaid on a periodic pattern object such as an insect screen door because the mesh pattern has periodicity such as in a grid and by preventing lightness/darkness unevenness created when a mesh pattern is made non-periodic in order to prevent moire.SOLUTION: This glass pane 10 includes on a transparent glass substrate 1 a mesh conductor layer 2 assuming a mesh pattern 2P defining many openings A, and the mesh pattern is formed from many boundary segments L which extend between two branching points B and define the openings and satisfies the three requirements, (a) the average N of the numbers of boundary segments extending from one branching point is in the range: 3.0≤N<4.0, (b) the shapes of the openings include two or more types of polygons selected from among pentagons, hexagons, and heptagons, provided that hexagonal openings are most preponderant, and (c) the polygons having the same number of sides are not identical in shape. A glass door 20 comprises the glass pane and a frame 3. |
