## Abstract

An electronic component includes an element body, a pair of external electrodes respectively disposed at both ends of the element body in a first direction, and a pair of metal terminals respectively connected to the pair of external electrodes with solder. Each metal terminal includes a connection opposing the corresponding external electrode in the first direction and formed with a plurality of grooves and includes a leg extending from the connection. The connection includes a pair of end edges separated from each other in a third direction intersecting with a second direction where the leg extends from the connection. The grooves extend in a direction different from the second direction and intersecting with the third direction so that the grooves are separated from one of the pair of end edges. A surface included in the connection and defining each of the grooves is in contact with the solder.

## Claims

### Claim 1

An electronic component comprising:
an element body;
a pair of external electrodes respectively disposed at both ends of the element body in a first direction;
a pair of metal terminals respectively connected to the pair of external electrodes with solder,
the metal terminals each including:
a connection opposing a corresponding external electrode of the pair of external electrodes in the first direction and formed with a plurality of grooves; and
a leg extending from the connection,
wherein the connection includes a pair of end edges separated from each other in a third direction intersecting with a second direction in which the leg extends from the connection,
the plurality of grooves extends in a direction different from the second direction and intersecting with the third direction in such a manner that the plurality of grooves is separated from one of the pair of end edges, and
a surface included in the connection and defining each of the grooves is in contact with the solder.

### Claim 2 (depends on 1)

The electronic component according to claim 1,
wherein at least one of the plurality of grooves reaches one end edge of the pair of end edges and is separated from another end edge of the pair of end edges.

### Claim 3 (depends on 2)

The electronic component according to claim 2,
wherein at least another of the plurality of grooves is separated from the one end edge and reaches the other end edge.

### Claim 4 (depends on 1)

The electronic component according to claim 1,
wherein the plurality of grooves formed in the connection of one metal terminal of the pair of metal terminals extends in a direction intersecting with a direction in which the plurality of grooves formed in the connection of another metal terminal of the pair of metal terminals extends when viewed in the first direction.

### Claim 5 (depends on 1)

The electronic component according to claim 1,
wherein the plurality of grooves is not formed in the leg.

### Claim 6 (depends on 1)

The electronic component according to claim 1,
wherein the metal terminal includes a plated layer constituting an outermost layer of the connection,
the plated layer including a Ni layer and a Sn layer disposed on the Ni layer.

### Claim 7 (depends on 6)

The electronic component according to claim 6,
wherein an outer surface of the plated layer includes the surface defining each of the grooves.

### Claim 8

An electronic component comprising:
an element body;
an external electrode disposed at an end of the element body in a first direction;
a metal terminal connected to the external electrode with solder,
the metal terminal including:
a connection opposing the external electrode in the first direction and formed with a plurality of grooves; and
a leg extending from the connection,
wherein the connection includes a pair of end edges separated from each other in a third direction intersecting with a second direction in which the leg extends from the connection,
