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-Fe 2 O 3 ≤0.80 (T-Fe 2 O 3 represents total iron oxide calculated as Fe 2 O 3 ) are satisfied. For the iron oxide in the composition, Fe 2+ /(Fe 2+ +Fe 3+ ), which represents the proportion by mass of Fe 2+ to 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. |
