Insertion guide device for endoscope and endoscope system

An endoscope system comprising:

• an endoscope including an insertion portion that extends in a longitudinal direction, has a distal end and a proximal end, and has a thin and tubular shape, an operation portion to which the proximal end of the insertion portion is connected and which is equipped with various operation members, and a cable extending from the operation portion;
• and
• an insertion guide device for an endoscope which guides insertion of the insertion portion,
• wherein the insertion guide device for an endoscope includes:
• a flat plate-shaped member that extends in the longitudinal direction of the insertion portion and has a width perpendicular to the longitudinal direction and a thickness perpendicular to the longitudinal direction and the width, the thickness being smaller than the width;
• and
• a holding member that attaches and holds a distal end portion of the insertion portion to a width direction side surface of the flat plate-shaped member,
• wherein the flat plate-shaped member has a bent portion that is bent in a thickness direction at a distal end, and
• wherein the holding member is arranged on a proximal end side with respect to the bent portion.
