Abstract
An electronic component includes a laminated capacitor and a substrate-type terminal including a substrate main body, first and second component connection electrodes, first and second external connection electrodes, and first and second connection electrodes. The substrate main body is made of a material and has a thickness that significantly reduces or prevents vibration being transmitted to a circuit substrate on which it is mounted.
