Abstract

In an embodiment, an electronic component with metal terminals includes: an electronic component 10 having a component body 11 of roughly rectangular solid shape, as well as external electrodes 12 provided on the ends thereof in the first direction d 1 , respectively; and metal terminals 20 provided in sets of two on each external electrode 12. Each metal terminal 20 has a first planar part 21 and a second planar part 23 oriented differently from the first planar part 21; the first planar part 21 is connected to each external electrode 12 in a manner facing one face of the component body 11; and the second planar part 23 is positioned in a manner facing at least partially, across a clearance 24, another face adjoining the one face of the component body 11, while being fixed to the component body 11 by an adhesive 40 provided in the clearance 24.

First claim
