Abstract:
After the periphery of the magnetic sensitive element is surrounded by an elastic member, the magnetic sensitive element is mold-formed with resin material. Soft epoxy or gel resin is employed as the elastic member, poured in an element-mounting space and solidified. The magnetic sensitive element is surrounded by silicone rubber. Such construction allows the magnetic sensitive element not to be affected by vibration and allows the elastic member to absorb the stress which is created due to the thermal deformation of the molded resin.
