A thin-film magnetic head for magnetic recording and reproducing apparatus includes a lower insulating layer deposited on a substrate and including a lower magnetic core, an intermediate insulating layer deposited on the lower insulating layer and including front and rear intermediate magnetic cores, and an upper insulating layer deposited on the intermediate insulating layer and including an upper magnetic core. The magnetic cores make up a magnetic circuit which has a magnetic gap defined between the lower magnetic core and the front intermediate magnetic core or between the front intermediate magnetic core and the upper magnetic core. A multiturn coil is embedded in the intermediate insulating layer to surround the rear intermediate magnetic core. The lower, intermediate, and upper insulating layers have respective flat surfaces including respective surfaces of the lower, intermediate, and upper magnetic cores. The lower, intermediate, and upper insulating layers are joined to each other through the flat surfaces.
