a second wiring substrate on which the first wiring substrate is stacked,

the interposer and the second electronic device are interposed between the first wiring substrate and the second wiring substrate, and

the first and second internal terminals of the interposer are configured to face the first electronic device through the first opening.

3. The test carrier according to claim 2 , further comprising a cover member which is laid on the base member so as to cover the first electronic device, wherein

the first electronic device is interposed between the base member and the cover member of the test carrier,

the cover member includes:

a film which covers the first electronic device; and

a frame which includes a second opening and to which the film is attached,

an accommodation space is provided between the base member and the cover member to accommodate the first electronic device, and

the accommodation space is decompressed relative to ambient air.

4. A test carrier comprising:

a base member on which a first electronic device under test is configured to be temporarily mounted; and

a second electronic device that is configured to be used to test the first electronic device, wherein

the second electronic device is mounted within the base member,

the second electronic device is configured to be electrically connected to the first electronic device,

the base member includes:

a first external terminal of the test carrier;

a first wiring that is configured to electrically connect the first electronic device to the first external terminal;

a second wiring that is configured to electrically connect the first electronic device to the second electronic device;

an interposer on which the second electronic device is mounted; and

a wiring substrate on which the first external terminal is provided and which holds the interposer,

the interposer includes:

a first main surface on which first and second internal terminals are provided, the first and second internal terminals being configured to contact first and second electrodes of the first electronic device; and
