A glass filler of the present disclosure includes glass having a composition, the composition including iron oxide. For the content in mass % of the iron oxide in the composition, 0.005≤FeO≤0.30 and 0.01≤T-FeO≤0.80 (T-FeOrepresents total iron oxide calculated as FeO) are satisfied. For the iron oxide in the composition, Fe/(Fe+Fe), which represents the proportion by mass of Feto total iron, is 0.15 or more and 1.00 or less. The glass filler of the present disclosure is a glass filler having a new composition including a coloring component, the glass filler having a high visible transmittance and a controlled color which can be, for example, within a range of colors different from those of conventional glass fillers that have a low visible transmittance.
