The projection-type illumination device according to claim 1, wherein the projection-type illumination device is configured to have a click-type structure so as to be movable in a front-rear direction. 4. A film holding means includes a plurality of fitting projections formed around a light-transmitting opening on the front surface of the light-shielding plate, and a plurality of film projections formed on the periphery of the film member so as to be engaged and held by the fitting projections. A concave groove and a plurality of fitting holes for fitting to the fitting protrusions so as to sandwich the film member engaged and held by the fitting protrusions through the recesses are provided around the periphery, and at least the center for light transmission is provided at the center. 4. The projection illuminating device according to claim 2, further comprising: a film holding portion having a non-light-transmitting portion formed by forming an opening so as to expose the entire opening. 5. The projection illuminating device according to claim 4, wherein the shape of the opening of the film holding portion is in conformity with various forms of the light transmitting opening. 6. The projection illuminating apparatus according to claim 1, wherein a dimension from a rear end of the illuminator main body to a front end of the lens barrel is shortened so as to be substantially in a palm.
