1. An irradiator comprising:
a first electrode to which a voltage is applied for generating a plasma; and
a holding member holding the first electrode;
wherein:
the holding member has a first member and a second member that are in contact with each other to constitute an accommodation space accommodating the first electrode;
a contact surface between the first member and the second member includes a non-perpendicular contact surface that is non-perpendicular to an axis of the first electrode; and
the non-perpendicular contact surface includes a first non-perpendicular contact surface, and a second non-perpendicular contact surface that is apart from the first non-perpendicular contact surface in a radial direction perpendicular to the axis.
