To provide a load-distributed type pavement block which makes a load applied to one block small by distributing a load applied from above, which prevents the up-and-down displacement and chipping of part of the block, which facilitates construction work of the block and makes it easy for people to walk on it, and which gives consideration to environment comprehensively.

The pavement block is symmetric with respect to a center point (1) in its side cross section. When the corner point (2-1) on the top surface and the corner point (3-1) on the undersurface are connected to each other by a straight line, the angle (4-1) which the straight line forms with a vertical line is not smaller than 20 degrees and not larger than 45 degrees. Then in the four corners of the side cross section, the angle (5-1, 5-2) which two sides form with each other, or the angle (5-1, 5-2) which the top and under surfaces and the tangent line to the sides form with each other in that part is in the range of 80 degrees - 100 degrees.
