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. Assuming that the number of the conductive linear bodies is N, a resistance value of a n-th conductive linear body counted from a side at which the first power feeder and the second power feeder are provided is rn, and a resistance value of the electrodes is R, all of conditions represented by numerical formulae (F1), (F2), and (F3) below are satisfied. (F1): r1/R≤300 (F2): rn+1≤rn (In the formula (F2), n is an integer of 1 or more) (F3): 0
