PROBLEM TO BE SOLVED: To provide a substrate for a temperature control mat capable of improving flexibility of length adjustment of temperature control piping. SOLUTION: A floor heating mat 1 includes a connecting body of the substrates A-H. Each of two grooves out of each groove group of a resin board 12 of the substrate A, a resin board 23 of the substrate C, a resin board 28 of the substrate E and a resin board 41 of the substrate H includes: first short grooves 45a, 45b extended from a portion near the edge on the front side of the resin board to a portion near the middle of the resin board in the longitudinal direction; second short grooves 46a, 46 extended from a portion near the edge on the back side of the resin board to the portion near the middle of the resin board in the longitudinal direction; a first connecting groove 47 for interconnecting ends on the back sides of the first short grooves 45a, 45b adjacent to each other; and a second connecting groove 48 for interconnecting ends on the front sides of the second short grooves 46a, 46b adjacent to each other. Since each warm water piping 4 is arranged in the first or second connecting groove 47, 48, the warm water piping 4 can be laid so as to be folded back in the vicinity of the middle in the extending direction of each resin board.
