摘要： There are provided a strength evaluation method of a die casting product capable of appropriately evaluating the strength of the die casting product, and a die casting product in which the strength is evaluated by the strength evaluation method. A breakage test is performed by a simple strength tester after casting, and then, a strength reduction ratio is estimated based on an area ratio of cold flakes in a broken surface obtained by broken surface observation. Alternatively, ultrasonic flaw detection is performed for an internal defect in a predetermined range of a high stress portion of the die casting product, calculated by stress analysis in advance, and the die casting product is evaluated to have a predetermined strength when a defect ratio obtained by dividing a total area of the internal defect in the predetermined range by a total defect detection area is less than or equal to a predetermined value.
