A compound has inhibitory activity on Discoidin Domain Receptor 1. The compound includes a urea derivative represented by the formula below or a pharmaceutically acceptable salt thereof. 

Urea derivative and use therefor

A compound has inhibitory activity on Discoidin Domain Receptor 1. A urea derivative is represented by the formula (I) or a pharmaceutically acceptable salt thereof: wherein, Ris trifluoromethyl, trifluoromethoxy, or pentafluorosulfanyl; each Ris independently a hydrogen atom or methyl which is optionally substituted by one hydroxyl or one saturated heterocyclyl having four to six ring-forming atoms; Ris a hydrogen atom, halogen atom, C-Calkyl, saturated heterocyclyl having four to six ring-forming atoms and optionally having an oxo group, or RO&#x2014;; and Ris phenyl, pyridyl, pyridazinyl, or pyrimidinyl, which phenyl, pyridyl, pyridazinyl, or pyrimidinyl is optionally substituted by one R.

The bonding sheet of the present invention comprises a substrate having an opening, and a low-melting point bonding metal which closes the opening or is arranged on the peripheral portion of the opening, to project in the opening. According to a bonding sheet of the present invention, a low-melting point bonding metal is interposed between a conductor pattern of a substrate and electrode terminals of an electronic component, and is bonded by thermocompression at a low temperature without melting the low-melting point bonding metal, so that bonding of a large number of electrode terminals can be completed by a single bonding operation.
