An electronic component of the invention has: a substrate; first to third terminal portions disposed on the substrate; and at least one spiral conductor portion disposed between the first and second terminal portions. The third terminal portion is not electrically connected to other portions of the substrate, and the first and second terminal portions are electrically connected to or disconnected from each other. In the electronic component, the number of production steps is smaller, the cost is lower, and a more highly accurate inductor component is realized as compared with a laminated electronic component in which emphasis is put on increase of the capacitor component. It is possible to realize an electronic component having accurate band- or low-pass filter characteristics.
