A laminated coil for motor having heat resistance and capable of voluminous production at a moderate cost, in which a conductive pattern 116 for coil is formed on a glass substrate 111, a glass coating 112 is applied on the conductive pattern 116 for oil, and further another conductive pattern 117 for coil is formed again on this glass coating 112. In a similar manner a glass coating 113, a conductive pattern 118 for coil, glass coating 114, and a conductive pattern 119 for coil are repetitively formed thereon, and finally a glass coating 115 is applied as a top coating, thereby making coils by thus laminating glass which have a high heat resistance and reliability for use under various environmental conditions. Furthermore, since, unlike a ceramic material, no baking as one body is required, there will never take place a disadvantage as the relation between the basing temperature of the ceramic and the melting point of the conductor for oil, thereby enabling enhancing the yield of coil production.
