## Abstract

An applicator according to one embodiment is an applicator for applying a sheet member to skin, and includes: a bottom plate facing the skin; a top plate facing the bottom plate and configured to be pressed toward the bottom plate; and a bending portion configured to apply the sheet member to the skin by bending the sheet member having advanced to the bending portion in a pressed state in which the top plate has been moved toward the bottom plate.

## Claims

### Claim 1

An applicator for applying a sheet member to skin, the applicator comprising:
a bottom plate facing the skin;
a top plate facing the bottom plate and configured to be pressed down toward the bottom plate;
a bending portion configured to apply the sheet member to the skin by bending the sheet member having advanced to the bending portion in a pressed state in which the top plate has been moved toward the bottom plate; and
a resisting portion configured to apply resistance to the sheet member advancing toward the bending portion at least in the pressed state,
wherein
the resisting portion includes a pressing member; and an elastic member configured to provide an elastic force for pressing the pressing member against the bottom plate, and
the resisting portion applies the resistance to the sheet member by nipping the sheet member advancing toward the bending portion with the bottom plate and the pressing member.

### Claim 2 (depends on 1)

The applicator according to claim 1, further comprising a guide configured to guide the sheet member toward the bending portion in the pressed state, and to prevent advancement of the sheet member toward the bending portion in a non-pressed state in which the top plate has not been moved toward the bottom plate.

### Claim 3 (depends on 1)

The applicator according to claim 1, further comprising a stopper configured to guide the sheet member toward the bending portion in the pressed state, and to prevent advancement of the sheet member toward the bending portion in a non-pressed state in which the top plate has not been moved toward the bottom plate.

### Claim 4 (depends on 3)

The applicator according to claim 3, wherein
the stopper includes a stopper body, and an elastic member providing the elastic force for pressing the stopper body against the bottom plate,
the top plate includes a protrusion enabled to be brought into contact with the stopper body,
in the non-pressed state, advancement of the sheet member is prevented by keeping the protrusion away from the stopper body such that the elastic force presses the stopper body against the bottom plate, and
the protrusion is brought into contact with the stopper body and the stopper is moved away from the bottom plate in a manner resisting against the elastic force in the pressed state, such that the sheet member is guided toward the bending portion.

### Claim 5 (depends on 1)

The applicator according to claim 1, further comprising an elastic member configured to generate the elastic force acting in a direction moving the bottom plate and the top plate away from each other.

### Claim 6 (depends on 1)

The applicator according to claim 1, wherein the sheet member is a microneedle sheet having a plurality of microneedles provided in a manner laid along a principle surface of the sheet.
