PROBLEM TO BE SOLVED: To provide a substrate material for a wall corner, which can improve workability during mounting by eliminating a curl caused by winding and easily and reliably deforming a shape from a flat expanded state to the bent state of making a cross-section assume an approximately L-shape. ! SOLUTION: Respective mutually adjacent one-side parts of a pair of strip-shaped parts 2a and 2b are connected together by a connection part 5. Elastic recoverability of the connection part 5 brings about recovery from a folded state, in which the respective strip-shaped parts 2a and 2b overlap each other, to an unfolded state in which each of the strip-shaped parts 2a and 2b makes an angle of 30°-120°. !
