PROBLEM TO BE SOLVED: To provide a planar heat pipe having a plurality of heat pipe parts, with excellent heat radiation performance, and capable of preventing the adjacent fellow heat pipe parts from being communicated each other. SOLUTION: A plurality of hollow hydraulic fluid sealing parts 5A, 5B independent each other is formed in a base plate 2 formed of two metal plates 3, 4 brazed each other, by bulging at least the one side metal plate 3. A hydraulic fluid is sealed into the hydraulic fluid sealing parts 5A, 5B to provide the plurality of heat pipe parts 6A, 6B juxtaposed vertically. Each of the heat pipe parts 6A, 6B has evaporation parts 15, 18, and condensing parts 16, 19 positioned in diagonal upper side of the evaporation parts 15, 18. A communication preventive penetrated through hole 8 for preventing the adjacent heat pipe parts 6A, 6B from being communicated each other is formed in a portion 7 between the adjacent heat pipe parts 6A, 6B in the one side metal plate 3.
