A computer monitoring system includes a sensor, a non-volatile storage and a controller. The surface of the molded electrical connection terminal section formed as a primary-molded article becomes exposed after secondary molding, and a stress-absorbing structure is formed in the primary molding resin section of the primary-molded article that serves as a transmission path for stresses associated with the resin shrinkage occurring when the secondary molding resin is cured. At least one second flexible band is provided with at least one second closure element that is complementary to the first closure element.
