Abstract
To provide a coil to be embedded in a road which is excellent in heat resistance and strength.SOLUTION: A sealing resin composition for a coil to be embedded in a road contains a thermosetting resin, wherein a deflection temperature under load measured under a condition according to JIS K 7191 is 140°C or higher. [Condition] A test piece of 10 mm×80 mm with thickness of 4 mm is obtained by curing the sealing resin composition for the coil to be embedded in the road. Then, flexural stress of 1.8 MPa is applied to a center of the test piece by a loading rod, while supporting a position of 8 mm from both ends in a longitudinal direction of the test piece in a heating bathtub. The temperature of a heating medium is raised at a rate of 2°C / min, in a state in which the flexural stress is applied thereto, and the temperature of the heating medium when deflection of the test piece reaches 0.34 mm is defined as a deflection temperature under load.SELECTED DRAWING: Figure 1
