## Abstract

A liquid injection jig set includes a chip receiver in which a microchip having a plate shape is received in a case, and a jig that is configured to be fittable to the chip receiver includes a hollow needle that can pierce a side end surface of the microchip, which is exposed from the case, and introduces liquid into the microchip via the hollow needle.

## Claims

### Claim 1

A liquid injection jig set comprising:
a chip receiver in which a microchip having a plate shape is received in a case; and
a jig that is configured to be fittable to the chip receiver includes a hollow needle that can pierce a side end surface of the microchip, which is exposed from the case, and introduces liquid into the microchip via the hollow needle.

### Claim 2 (depends on 1)

The liquid injection jig set according to claim 1,
wherein the chip receiver is positioned to and fitted to the jig.

### Claim 3 (depends on 2)

The liquid injection jig set according to claim 2,
wherein the chip receiver is positioned in a right-left direction and an up-down direction.

### Claim 4 (depends on 1)

The liquid injection jig set according to claim 1, further comprising:
a structure that regulates a fitting direction of the chip receiver to the jig.

### Claim 5 (depends on 2)

The liquid injection jig set according to claim 2,
wherein the jig has a structure enabling pinching of the chip receiver.

### Claim 6 (depends on 5)

The liquid injection jig set according to claim 5,
wherein the jig includes two plate portions opposite to each other, and the chip receiver is fitted to a gap between the two plate portions.

### Claim 7 (depends on 6)

The liquid injection jig set according to claim 6,
wherein the respective plate portions are different in length and/or width.

### Claim 8 (depends on 7)

The liquid injection jig set according to claim 7,
wherein a reaction field formed in the microchip can be visually confirmed through at least either one of the two plate portions, in a state where the chip receiver is fitted to the jig.

### Claim 9 (depends on 8)

The liquid injection jig set according to claim 8,
wherein the liquid is subjected to negative pressure suction into the microchip when the hollow needle pierces the microchip.

### Claim 10 (depends on 9)

The liquid injection jig set according to claim 9,
wherein the microchip is configured to have a substrate layer including a polydimethylsiloxane layer, and
wherein the hollow needle pierces the polydimethylsiloxane layer.

### Claim 11

A chip receiver comprising:
a microchip having a plate shape; and
a case capable of receiving the microchip,
wherein the case is configured to be fittable to a jig that has a hollow needle that can pierce a side end surface of the microchip and introduces liquid into the microchip via the hollow needle, and
wherein the side end surface of the microchip is exposed in a state where the microchip is inserted in the case.

### Claim 12 (depends on 11)

The chip receiver according to claim 11, further comprising:
a structure that regulates an insertion direction of the microchip into the case.

### Claim 13 (depends on 12)

The chip receiver according to claim 12,
wherein the chip receiver includes a locking portion that restricts movement of the microchip received in the case.

### Claim 14

A jig comprising:
a structure which enables fitting of a chip receiver in which a microchip having a plate shape is received in a case; and
a hollow needle that can pierce a side end surface of the microchip, which is exposed from the chip receiver,
wherein liquid is introduced into the microchip via the hollow needle.
