WIRING SHEET AND SHEET-FORM HEATER

A wiring sheet includes: a pseudo sheet structure including a plurality of conductive linear bodies arranged at intervals; a pair of electrodes; and a first power feeder provided for one of the electrodes and a second power feeder provided for the other of the electrodes, in which provided that the number of the conductive linear bodies is N, a resistance value of each conductive linear body is r, a resistance value of each electrode is R, a resistance value of each electrode between the n-th conductive linear body and the (n−1)th conductive linear body counted from a side at which the first power feeder and the second power feeder are provided is Rn, the wiring sheet satisfies all conditions represented by numerical formulae (F1) to (F3) below,r/R≤300 (F1)Rn≤Rn−1 (F2)where n is an integer of 2 or more,0
