The present invention relates to a cap with lighting lamp which is suitable for mountain climbing or fishing at night. Traditionally, a hand-held lighting device is used for mountain climbing or fishing at night. However, such a hand-held lighting device is not convenient in use. Therefore, it has been proposed that a lighting device (lamp) is retained on a user's head or clamping on the visor of a hat. However, such techniques suffer the drawbacks of easy dismounting when acted upon by wind pressure or hit by a foreign object. Furthermore, when a light illuminates towards the front, the light can not be concentrated. The present invention is aimed to solve the above problems, and having an object to provide a cap having a body 1 on one side of which a battery (alkaline battery) is installed. When used for mountain climbing or fishing at night, the plurality of bulbs (LED) illuminate towards one direction just like projectors (floodlight). Also, the lighting angle of the bulbs will not alter even receiving wind flow or object impacts and the bulbs will not fall off.
