Abstract: In the electronic component, the second portion of the diffusion prevention layer extends parallel to the main surface of the base material. When the electronic component is surface-mounted on the mounting substrate, the conductive bonding material such as solder is interposed between the electrodes of the electronic component and the land electrodes of the mounting substrate. In the case that the bonding surface between the diffusion prevention layer and the substrate is wide, it is difficult for the metal component of the bonding material to reach the body portion of the electrodes through the bonding surface. Therefore, a situation in which metal component of the bonding material diffuse into the body portion is suppressed, and a decrease in strength of the electrodes due to the diffusion is suppressed.
