PURPOSE: To improve workability at the time of mounting while preventing a constraint on a design in a transformer for EL of a clock. CONSTITUTION: A primary winding 12 and a secondary winding 13 are stored in the annular recessed section 11b of a thick discoid ferrite core 11 while a rigid terminal strip 14 is Stored. The projecting sections 18, 19 of the terminal strip 14 are projected to the outside through the notches 11c, 11d of the ferrite core 11. The terminals 12a, 12b, 13a, 13b of the windings 12, 13 are wound on terminal sections 18a, 18b, 19a, 19b formed to the projecting sections 18, 19. A discoid permalloy plate 15 is superposed on one surface side of the ferrite core 11, thus covering the annular recessed section 11b and the notches 11c, 11d. |
