PURPOSE:To fit pins easily, and to mount the pins firmly to a substrate by projecting a plurality of the pins, tip sections thereof are insert-molded and fixed into the substrate, from the substrate. CONSTITUTION:A substrate 1 for mounting an electronic part chip is formed by a molded shape from a synthetic resin while a plurality of pins 2, 2..., tip sections thereof are insert-molded and fastened into the substrate 1, are projected from the substrate 1. The outer circumferences of the base sections of at least two pins 2 of a plurality of the pins 2, 2... are covered with positioning projecting sections 3 integrally protruded from the substrate 1. Consequently, the pins 2 are easily fixed firmly by insert molding, and the formation of collars for positioning to a mother board of the pins 2 is unnecessitated by the positioning projecting sections 3 integrally projected from the substrate 1. When a recessed section for mounting the chip is further shaped, the recessed section can be formed at the same time as the molding of the substrate 1. |
