The catheter device according to one embodiment of the present invention is provided with: a tube to be inserted in a human body; and a light emission part which is provided to the leading end side of the tube and emits an infrared beam for confirmation of the position of the tube. The light emission part has: a base material that extends in the tube extension direction; a first infrared emission element which is mounted to the base material and which has an optical axis in a first direction orthogonal to the extension direction; and a second infrared emission element which is mounted to the base material, which has an optical axis in a second direction being orthogonal to the extension direction and being different from the first direction, and which is disposed so as to be juxtaposed to the first infrared emission element in the extension direction. This configuration enables detecting of the position of the tube properly without making the leading end of the tube of the catheter device thicker than necessary.
