## Abstract

Strength of a resin case is improved. A continuous fiber sheet includes a bottom surface portion which forms a bottom surface of the resin case, an erected wall portion which is erected from the bottom surface portion and forms a peripheral wall of the resin case, and a stepped portion in which the continuous fiber sheet connecting the bottom surface portion and the erected wall portion to each other is bent like steps along the peripheral wall. A resin member includes a rib portion which is bonded to the stepped portion and extends from the stepped portion toward an outer edge of the resin case.

## Claims

### Claim 1

A resin case comprising:
a continuous fiber sheet; and
a resin member bonded to the continuous fiber sheet,
the continuous fiber sheet including
a bottom surface portion which forms a bottom surface of the resin case,
an erected wall portion which is erected from the bottom surface portion and forms a peripheral wall of the resin case, and
a stepped portion in which the continuous fiber sheet connecting the bottom surface portion and the erected wall portion to each other is bent like steps along the peripheral wall,
the resin member including
a rib portion which is bonded to the stepped portion and extends from the stepped portion toward an outer edge of the resin case and extends substantially orthogonal to the bottom surface, and
a lateral rib portion which is arranged closer to the outer edge of the resin case than the rib portion and extends substantially in parallel to the bottom surface.

### Claim 2 (depends on 1)

The resin case according to claim 1, wherein
the resin member includes a plurality of rib portions.

### Claim 3 (depends on 1)

The resin case according to claim 1, the resin case being substantially in a shape of a polygon in a plan view, wherein
the rib portion is provided in a central portion of a side of the polygon.

### Claim 4 (depends on 1)

The resin case according to claim 1, wherein
the resin member includes a plurality of lateral rib portions.

### Claim 5 (depends on 1)

The resin case according to claim 1, the resin case being substantially in a shape of a polygon in a plan view, wherein
the lateral rib portion is provided in a central portion of a side of the polygon.

### Claim 6 (depends on 4)

The resin case according to claim 4, the resin case being substantially in a shape of a polygon in a plan view, and wherein
the lateral rib portion is provided in a central portion of a side of the polygon.

### Claim 7 (depends on 2)

The resin case according to claim 2, the resin case being substantially in a shape of a polygon in a plan view, wherein
the rib portion is provided in a central portion of a side of the polygon.
