Abstract: PURPOSE:To suppress the inner linear expansion coefficient for manufacturing the title electronic parts having high reliability. CONSTITUTION:A protective resin 10 is provided with an intermediate layer 11, an inner side layer 12 formed between the in-termidiate layer 11 and a circuit substrate 3 as well as an outer side layer 13 between the intermediate layer 11 and a resin sealer 4.
