Abstract: A conductive terminal includes an inner electrode part, an opening edge electrode part, and a lateral electrode part. The inner electrode part is connectable to a terminal electrode of a chip component by being inserted along an inner wall of an accommodation recess of a case. The opening edge electrode part is formed continuously to the inner electrode part. The lateral electrode part is formed continuously to the opening edge electrode part along an outer surface of the case. The inner electrode part includes a base part, a curved part, and a continuous boundary part. The base part continues to the opening edge electrode part. The curved part is formed near a tip of the base part and protrudes away from the lateral electrode part. The continuous boundary part is formed between the base part and the curved part and continuously connects them.
