(1) Banaras Hindu University, Varanasi, India

Wavelet transform of a distribution in $\mathscr{M}_{\omega}^{'}$ involving wavelet of infraexponential decay (subexponential decay) is studied. An inversion formula is obtained which is valid in the weak topology of $\mathcal{D}^{'}$. A discussion on extension of the results to ultradistribution space of compact support is also given.
