A series of electronic components stored in a tape include a plurality of electronic components each arranged such that a first main surface faces a bottom surface of a cavity. In each electronic component, on a first side surface, a thickness in a width direction of a first terminal electrode at a first main surface side is smaller than a thickness in the width direction of the first terminal electrode at a second main surface side, and on a second side surface, a thickness in the width direction of a second terminal electrode at the first main surface side is smaller than a thickness in the width direction of the second terminal electrode at the second main surface side.
