An indwelling needle device includes a shield tube with a flexible outer needle fixed at a front end, a hub movable in a lumen of the shield tube, an infusion tube attached to an end thereof, a rigid inner needle at a front end part of the hub and insertable into a lumen of the outer needle. A lateral penetration path penetrates to a lumen of the hub. A space is provided between an outer surface of the hub and an inner surface of the shield tube. A sealing section is on the outer surface of the hub. The outer peripheral surface of the hub forms engagement recesses. A rear-end-side engagement projection is on the inner surface of the shield tube and engages with the engagement recesses. Hub side walls, with a communication area opening, couple with the front end of the hub. The hub can be small in size.
