PROBLEM TO BE SOLVED: To provide a thin and inexpensive elevator control board. SOLUTION: This elevator control board 1 for internally storing a heat pipe cooler is constituted such that opening parts are arranged in two surfaces opposed at the shortest distance in parallel to the vertical direction on this elevator control board, and a heat radiating fin part 4 and a cooling fan 5 of the heat pipe cooler are arranged between the opening parts, and a cooling wind taken in from one of the opening parts by the cooling fan is blown off from the other opening part by passing through the heat radiating fin part. |
