TABULAR HEAT PIPE

PROBLEM TO BE SOLVED: To provide a tabular heat pipe capable of approximating a temperature detected by a temperature detecting part of a heating element attached to a heating element attaching part to a temperature near an actual temperature of the heating element. SOLUTION: The tabular heat pipe 1 is provided with a substrate 2 formed by two metal plates joined together. The heating element attaching part 5 and a heat radiation part 6 are provided on the substrate 2. A heat pipe part 8 laid across the heating element attaching part 5 and the heat radiation part 6 is formed on the substrate 2. The heat pipe part 8 is provided with an evaporation part 10 existing on the heating element attaching part 5 in the heat pipe part 8, and a bypass part 13 communicating a condensing part 11 with a portion existing on the heat radiation part 6. A temperature detection position 14 for detecting the temperature by the temperature detecting part S1 of the heating element S attached to the heating element attaching part 5 is provided in a portion provided with the bypass part 13 in the heating element attaching part 5 of the substrate 2.
