Insert molding and insert molding quality determination device

An insert molding quality determination device that determines quality of an insert component after the insert component is resin-molded, the insert molding quality determination device comprising:

• a sensing signal input unit that is supplied with a sensing signal from a sensor disposed close to the insert component that is a quality determination target, to sense a state around the insert component during resin molding;
• a first determination unit that is configured to perform, after the resin molding, a first determination to determine whether the resin molding is normal or abnormal based on the sensing signal;
• a measurement unit that is configured to measure a first electrical property of the insert component, which is the quality determination target, before the resin molding of the insert component and that measures a second electrical property of the insert component after the resin molding;
• an electrical property storage unit that stores the first electrical property measured by the measurement unit;
• and
• a second determination unit that is configured to perform a second determination to determine whether the resin molding is normal or abnormal by comparing the first electrical property stored in the electrical property storage unit and the second electrical property measured by the measurement unit after resin molding and making the second determination based on a result of the comparison,
• wherein the sensing signal supplied to the sensing signal input unit and that is used in the first determination by the first determination unit indicates information that is different from the first electrical property and the second electrical property that are measured by the measuring unit and that are used in the second determination by the second determination unit.
