Bulb type fluorescent lamp and illuminator

The present invention provides a self-ballasting fluorescent lamp (1) which can obtains an external appearance that is approximate same to the common illuminating electric bulb and reduces the heat influence of the luminous tube (4) to the electronic component (60) that is configured at the inner side of the lamp holder (2). One end side of the cover body (3) is arranged with a lamp holder (2) and the other end side of the cover body (3) is supported with a luminous tube (4). The substrate (58) of the lighting device (7) is installed with an electronic component (60) of the light circuit (59) which lights the luminous tube (4). The substrate (58) is formed to a breadth dimension that can be inserted in the inner side of the lamp holder (2) and is longitudinally arranged along the center line direction of the lamp holder (2), the cover body (3) is minimized to obtain an external appearance approximately same to the common illuminating electric bulb. The heat insulating material (64) is arranged at the opening between the longitudinally arranged substrate (58) and the cover body (3). The heating insulating material (64) is used for insulating the heat between the side of the lamp holder (2) and the side of luminous tube (4) and reducing the heat influence of the luminous tube (4) to the electronic component (60) arranged at the inner side of the lamp holder (2). At the inner side of the lamp holder (2) the front end part of the tubule (38) enveloped with main mercury alloy (39) is thermally connected with one part of electronic component (60) and the lamp holder (2) by the heat conducting material (65).
