ABSTRACT:
To prevent the lead terminals of an electronic circuit component from being bent due to the vibration of the component after being mounted on a circuit board, each lead terminal has a tapered portion formed between an inserted tip portion and a cut dumb bar portion and having a width which decreases from the dumb bar portion toward the tip portion to prevent stresses from concentrating in the terminal.
