The two types of high explosives are Primary explosives, which are easily ignited or detonated and are very sensitive to heat and friction, and Secondary explosives, which are usually much less sensitive to heat and friction and they typically have to be ignited through the use of other explosive materials.
Cos if you throw them in a fire they will burn, of course the wooden part usually lights up at the same time so that's a chicken and egg type example. It would depend on the specific matches composition and structure as to what amount of friction energy will ignite it. And if you meant how hot is the flame on a match; that'll depend on the composition of the match head and the material used for the stick. So 'a high temperature' is the answer.
