A method for producing an inorganic fiber having a large fiber diameter of 3 μm or more and substantially free of shots is provided. An inorganic fiber having SiO 2 , CaO, and MgO as essential components, the silicon content is 5 mol% to 80 mol%, the calcium content is 5 mol% to 80 mol%, Magnesium content is 2 mol% or more and 80 mol% or less (however, the content is mol% of each element with respect to the total amount of elements other than oxygen in the inorganic fiber), and substantially An inorganic fiber characterized by not containing aluminum, having an average fiber diameter of 3 μm or more and 50 μm or less, and no shots of 50 μm or more.
