Ophthalmic forceps comprising: a tubular body; a pair of neck portions; a pair of slit formation portions provided on a tip end side of the neck portions; a pair of gripping portions provided on a tip end side of the slit formation portions; and substantially S-shaped portions formed at portions extending from the neck portions to the slit formation portions, wherein when the tubular body slides to house an entirety of the neck portions in an inner cavity of the tubular body, gripping surfaces of the gripping portions are in surface contact with each other, and a slit is formed between the pair of slit formation portions, each substantially S-shaped portion includes a first curved portion curving outward from a center axis of the tubular body and a second curved portion curving inward to the center axis of the tubular body and positioned on a gripping portion side, characterized in that: a thickness of each slit formation portion is greater than a thickness of each neck portion, at a position of connection between each neck portion and each slit formation portion, a step at an opposite side to the slit is formed due to a difference in the thickness between the each slit formation portion and the each neck portion, and in a state in which the gripping surfaces are in surface contact with each other, a distance from the center axis of the tubular body to an outer edge of each neck portion at an end surface position of the tubular body is equal to or less than a radius of the inner cavity of the tubular body, and is greater than a distance obtained by subtraction of a height of the step from the radius of the inner cavity of the tubular body. a tubular body; a pair of neck portions; a pair of slit formation portions provided on a tip end side of the neck portions; a pair of gripping portions provided on a tip end side of the slit formation portions; and substantially S-shaped portions formed at portions extending from the neck portions to the slit formation portions, wherein when the tubular body slides to house an entirety of the neck portions in an inner cavity of the tubular body, gripping surfaces of the gripping portions are in surface contact with each other, and a slit is formed between the pair of slit formation portions, each substantially S-shaped portion includes a first curved portion curving outward from a center axis of the tubular body and a second curved portion curving inward to the center axis of the tubular body and positioned on a gripping portion side, characterized in that: a thickness of each slit formation portion is greater than a thickness of each neck portion, at a position of connection between each neck portion and each slit formation portion, a step at an opposite side to the slit is formed due to a difference in the thickness between the each slit formation portion and the each neck portion, and in a state in which the gripping surfaces are in surface contact with each other, a distance from the center axis of the tubular body to an outer edge of each neck portion at an end surface position of the tubular body is equal to or less than a radius of the inner cavity of the tubular body, and is greater than a distance obtained by subtraction of a height of the step from the radius of the inner cavity of the tubular body. a thickness of each slit formation portion is greater than a thickness of each neck portion, at a position of connection between each neck portion and each slit formation portion, a step at an opposite side to the slit is formed due to a difference in the thickness between the each slit formation portion and the each neck portion, and in a state in which the gripping surfaces are in surface contact with each other, a distance from the center axis of the tubular body to an outer edge of each neck portion at an end surface position of the tubular body is equal to or less than a radius of the inner cavity of the tubular body, and is greater than a distance obtained by subtraction of a height of the step from the radius of the inner cavity of the tubular body.
