The present invention provides an epoxy resin composition for sealing a geomagnetic sensor module comprising an epoxy resin, a curing agent and a phase transition material, and a geomagnetic sensor module sealed with the epoxy resin composition. In the present invention, by using a sealing material including a phase transition material, there is an advantage that the geomagnetic sensor can be maintained at a constant temperature with respect to an external temperature change. |
