## Abstract

A test carrier carried in a state of accommodating a device under test (DUT) includes: a carrier body that holds the DUT; a lid member that covers the DUT and is attached to the carrier body; and an identifier for identifying an individual of the test carrier.

## Claims

### Claim 1

A test carrier carried in a state of accommodating a device under test (DUT), the test carrier comprising:
a carrier body that holds the DUT;
a lid member that covers the DUT and is attached to the carrier body; and
an identifier for identifying of the test carrier, wherein
the identifier is associated with first information about the test carrier,
the carrier body includes:
contactors provided to correspond to terminals of the DUT;
external terminals electrically connected to the contactors; and
a first through-hole for positioning that is provided to face the DUT, and
the identifier includes a correction value corresponding to an error of a relative position of the first through-hole with respect to the contactor.

### Claim 2 (depends on 1)

The test carrier according to claim 1, wherein the identifier is formed on the test carrier.

### Claim 3 (depends on 1)

The test carrier according to claim 1, wherein
the carrier body includes:
the external terminals;
internal terminals provided to face the contactors; and
a wiring pattern that connects the internal terminals and the external terminals to each other, and
the identifier includes an electrical resistance value of the test carrier.

### Claim 4 (depends on 1)

The test carrier according to claim 1, wherein the identifier is associated with second information about the test carrier.

### Claim 5 (depends on 4)

The test carrier according to claim 4, wherein the second information indicates the identified test carrier.

### Claim 6 (depends on 4)

The test carrier according to claim 4, wherein second information includes a test result of the DUT.
