An electronic device comprising a surface-treating layer formed on at least a part of a surface thereof, the surface-treating layer being formed of a (poly)ether group-containing silane compound represented by any of the formulae (A1), (A2), (B1), (B2), (C1), or (C2). In the formulae, PFPE is each independently at each occurrence a group represented by - (OC<sub>6</sub>F<sub>12</sub>)<sub>a</sub>-(OC<sub>5</sub>F<sub>10</sub>)<sub>b</sub>-(OC<sub>4</sub>F<sub>8</sub>)<sub>c</sub>-(OC<sub>3</sub>X<sup>F</sup><sub>6</sub>)<sub>d</sub>-(OC<sub>2</sub>F<sub>4</sub>)<sub>e</sub>-(OCF<sub>2</sub>)<sub>f</sub>- and having at least one branched structure, or a group represented by the formula: - (R<sup>16</sup>R<sup>17</sup>)<sub>j1</sub>-. The symbols are as defined in the description. |
