An iron type head body comprises: a material body 13 made from a forgeable metal; and a disparate metallic member 12 made from a metal having nearly equal or smaller specific gravity than the material body 13, and different constituents. By providing the disparate metallic member 12 inside the upper portion of the head body not adjacent to the sole, the head can be lightened. Moreover, by confining the disparate metallic member 12 in the portion upside of the sole 4 not adjacent to the sole 5, the head body 11 can be hypobaric, while the C.G. of the head 2 can be lowered entirely in addition to being lightened.

A ceramic board is formed in an almost rectangular shape and has one side surface of an outer peripheral surface formed as an abutting surface, which is caused to abut on positioning surfaces of a radiating member, and one surface in a vertical direction formed as a device disposing surface on which a semiconductor light emitting device is to be disposed. Predetermined conductive patterns are formed on the ceramic board. A light emitting portion has a semiconductor light emitting device. A pair of positive and negative planar electrode portions are formed on the ceramic board and connected to the semiconductor light emitting device through the conductive patterns. At least a part of the pair of planar electrode portions are set to be exposure regions exposed to the device disposing surface of the ceramic board and the exposure regions are positioned in portions other than a portion linked to the abutting surface in an outer peripheral portion of the device disposing surface.

A lighting controller for a lighting device for a vehicle includes a semiconductor light source; a power source for supplying electric power; and control circuitry for receiving the electric power from the power source and controlling a current supplied to the semiconductor light source. The control circuitry determines an amount of time the semiconductor light source is in a turned on state and an amount of time the semiconductor light source is in a turned off state. The control circuitry controls a value of the current supplied to the semiconductor light source based on both the determined amount of time the semiconductor light source is in a turned on state and the determined amount of time the semiconductor light source is in a turned off state.
